How to Convert Square Feet to Cubic Feet

Three Methods:

Converting square feet to cubic feet is easy, as long as you know the depth or height of the final object. Cubic feet is a measure of volume, meaning you need a length, width, and depth measurement. However, since square already accounts for length and width, converting is easy.

Steps

Square Feet to Cubic Feet Converter

Finding Cubic Feet

  1. Make sure that all of your measurements are in feet.If you make one measurement in feet, you need to make them all in feet. You cannot measure the length in inches and the width in feet, otherwise your answer won't have any meaning. If you need to make the measurements yourself, make sure they are in the same scale. If you've been given different units, you can convert them as follows:
    • If given inches...divide the measurement by 12 (ex.2ft2{\displaystyle 2ft^{2}}. If you've got a room you want cubic footage off,the base is the square footage of the floor.
    • The height, or how tall the space is, is always measured from base to base, at the same point on each. So if you measure from the corner of the floor, you need to go to the same corner in the ceiling.
    • A regular prism is one where the two bases are even and equal polygons, such as triangles, squares, circles, diamonds, etc.
  2. Multiply the base by the height to get the cubic footage of regular shapes.The easiest way to see this is to think of the volume of a rectangle, found using the basic formulaLength∗Width∗Height{\displaystyle Length*Width*Height}. Since square footage is found by multiplying length and width, all you have to do now is account for the height. This same principle applies no matter what the base is -- simply multiply square footage by height.
    • Square Footage =12ft2{\displaystyle 12ft^{2}}, Height =3ft{\displaystyle 3ft}
      • 12ft2∗3ft={\displaystyle 12ft^{2}*3ft=}36cubic feet
    • Square Footage =4ft2{\displaystyle 4ft^{2}}, Height =6ft{\displaystyle 6ft}
      • 4ft2∗6ft={\displaystyle 4ft^{2}*6ft=}24cubic feet
    • Square Footage =1.5πft2{\displaystyle 1.5\pi ft^{2}}, Height =2ft{\displaystyle 2ft}
      • 1.5πft2∗2ft={\displaystyle 1.5\pi ft^{2}*2ft=}9.42cubic feet
  3. Convert the square footage of a sphere by multiplying the surface area byr3{\displaystyle {\frac {r}{3}}}, where r is the sphere's radius.If you're given the surface area of a sphere and the radius, you can convert to cubic footage with ease. Simply multiply the surface area by the radius, then divide by three:
    • Surface Area =314.16ft2{\displaystyle 314.16ft^{2}}, Radius=5ft{\displaystyle 5ft}
      • 314.16ft2∗53={\displaystyle 314.16ft^{2}*{\frac {5}{3}}=}523.6cubic feet
    • Note,however, that the formula for the volume of a sphere is simplyV=43π∗r3{\displaystyle V={\frac {4}{3}}\pi *r^{3}}It is often easier to plug in "r" for this equation than to try and convert from square footage.
  4. Always express your answer in cubic feet after solving.This is a simple way to keep track of measurements whether you're building a garden or finishing up your homework. To finish you answer, you must denote the type of measurements so that a builder, teacher, or friend knows whether "523.6" refers to inches, yards, feet, miles, etc. Remember: volume isalwayscubed. There are three acceptable ways to write the units for cubic feet.
    • 523.6ft3{\displaystyle 523.6ft^{3}}
    • 523.6{\displaystyle 523.6}cubic feet.
    • 523.6{\displaystyle 523.6}feet cubed
  5. Practice with an example.The following question should not be difficult, as long as you remember how the correct equation. The answer can be found by clicking and highlighting after the second bullet.
    • You have a carrot and potato garden with a square footage of120ft2{\displaystyle 120ft^{2}}. The bed is two feet deep. What is the volume of the garden in cubic feet?
    • The cubic feet measurement is240ft3{\displaystyle 240ft^{3}}(120ft2x2ft=240ft3){\displaystyle (120ft^{2}x2ft=240ft^{3})}

Understanding and Using Your Measurements

  1. Know how to spot questions asking for cubic footage.Not all questions are going to tell you outright that they want you to find cubic footage. What you need to remember is that cubic footage is just a measurement of volume -- so any volume question you're asked with feet in the measurements (ft3{\displaystyle ft^{3}}), is likely asking for cubic feet. Some example problems might ask:
    • If the square footage is10ft2{\displaystyle 10ft^{2}}, and the height is5ft{\displaystyle 5ft}, what is the volume?
    • What is the volume, in feet, of the garden?
    • How many cubic feet of water could fit in a square box with a base of23ft2{\displaystyle 23ft^{2}}and a height of2ft{\displaystyle 2ft}? (Note: "base" means the flat bottom, or square footage.
  2. Purchase mulch, soil, and other commodities sold by cubic footage only after you know the thickness you need for your project.This is best seen in an example. Say you have a 100 square foot backyard area to plant a garden and need to know how much topsoil to buy. Before buying anything, you need to know how deep your soil will go. This is your "height" measurement, telling you how high the soil must go. For example, say you need, at minimum 6-inch holes for each plant:
    • Make sure all units are in feet:
      • 50ft3{\displaystyle 50ft^{3}}of soil to fill your garden.
  3. Convert cubic feet back into square footage by dividing the height from the cubic footage.Since it is such a simple conversion to get to square footage, it is simple to undo. For example, you might have a heater capable of filling a6800ft3{\displaystyle 6800ft^{3}}, but you want to know how much floor-space that covers in your room. To find out, simply divide 6800 by the height of the room, found by simply measuring floor to ceiling:
    • Example height of the room =12ft{\displaystyle 12ft}
    • 6800ft312fr=566.67ft2{\displaystyle {\frac {6800ft^{3}}{12fr}}=566.67ft^{2}}
    • The heater will heat a room with a square footage is566.67ft2{\displaystyle 566.67ft^{2}}and a height of 12ft.
      • This strategy is purely for rectangular or cylindrical volumes. It is much more complex for pyramids and spheres.
  4. Remember that this conversion only works for regular prisms and spheres.If your shape curves, bends, twists, or is otherwise irregular, you cannot simply convert from square footage to cubic footage. If the object changes size or thickness as it gains height than the measurement of the base -- your square footage -- will no longer be accurate. These types of problems usually require the integral calculus to solve.
    • Imagine buying a heater for a room with a pointed ceiling. Now imagine how much more of the room you'd have to heat if the room was perfectly square, instead of pointed at the top. While the square footage of the floor is important, it isn't the only thing determining the cubic footage.

  • Question
    How many square feet does one cubic foot equal?
    wikiHow Contributor
    Community Answer
    They are different things entirely. A square foot is a two-dimensional measurement, whereas a cubic foot is a three-dimensional measurement (e.g. the volume of a room). One is not convertible to the other.
    Thanks!
  • Question
    How can I tell how many cubic feet of top soil I need?
    Top Answerer
    Decide how deep you want to spread the topsoil. Multiply the depth by the area you're covering. That gives you the volume of topsoil you need.
    Thanks!
  • Question
    How can I convert 420 square feet into cubic feet?
    Top Answerer
    You would need an additional measurement, such as height or depth. Without that third measurement, square feet are not convertible to cubic feet.
    Thanks!
  • Question
    How do I convert cubic feet to square feet?

    Cubic feet and square feet are not convertible to each other. The first is a measure of volume; the second is a measure of area.
    Thanks!
  • Question
    I have 888 sq feet area, how many bags of rock at 4 cf each bag will I need?
    Top Answerer
    If you're going to deal with the volume (cf) of each bag, you will need to know the volume of the storage area. If you're dealing with the area (sq ft) of the storage area, you will need to know how much area each bag takes up (in sq ft).
    Thanks!
  • Question
    Trash will pick up 4 cubic feet max. I have an item 24" x 60" x 20". Will they pick this up?
    Top Answerer
    No, that item is well over 4 cu ft.
    Thanks!
  • Question
    How tall is 300 cubits?
    Top Answerer
    There are various (slightly different) definitions of a cubit, but it's commonly thought of as 18 inches.
    Thanks!
  • Question
    How many cubic feet of mulch do I need to cover 78 feet at 2-feet deep?
    Top Answerer
    If you mean 78 square feet to be covered by 2 feet of mulch, the volume is 156 cubic feet.
    Thanks!
  • Question
    How many cubic feet of mulch do I need to cover 200 square feet one inch thick?
    Top Answerer
    Multiply 200 square feet by one-twelfth of a foot (one inch) to get the volume. That's the same as dividing 200 by 12: 16 2/3 cubic feet.
    Thanks!

Quick Summary

To convert square feet to cubic feet for regular shapes, multiply the base by the height. The volume of a regular shape is found by multiplying length by width by height, and since square footage is found by multiplying length and width, all you have to do is account for the height! This same principle applies no matter what the base is. Don't forget to express your answer in cubic feet after solving!

Did this summary help you?
  • Always check your work by dividing your final answer by the height. You should end back up at the original square footage.
