If given inches. . . divide the measurement by 12 (ex. 24in12=2ft{\displaystyle {\frac {24in}{12}}=2ft}). If given centimeters. . . divide by 30. 48 (ex. 150cm30. 48=4. 92126ft{\displaystyle {\frac {150cm}{30. 48}}=4. 92126ft}). If given yards. . . multiply the measurement by 3 (ex. 3yds∗3=9ft{\displaystyle 3yds*3=9ft}).
The area of the base is always in square footage, such as 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] X Research source
Square Footage = 12ft2{\displaystyle 12ft^{2}}, Height = 3ft{\displaystyle 3ft} 12ft2∗3ft={\displaystyle 12ft^{2}*3ft=} 36 cubic feet Square Footage = 4ft2{\displaystyle 4ft^{2}}, Height = 6ft{\displaystyle 6ft} 4ft2∗6ft={\displaystyle 4ft^{2}*6ft=} 24 cubic 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. 42 cubic feet[4] X Research source

You have a carrot and potato garden with a square footage of 120ft2{\displaystyle 120ft^{2}}. The bed is two feet deep. What is the volume of the garden in cubic feet? The cubic feet measurement is 240ft3{\displaystyle 240ft^{3}} (120ft2x2ft=240ft3){\displaystyle (120ft^{2}x2ft=240ft^{3})}
If the square footage is 10ft2{\displaystyle 10ft^{2}}, and the height is 5ft{\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 of 23ft2{\displaystyle 23ft^{2}} and a height of 2ft{\displaystyle 2ft}? (Note: “base” means the flat bottom, or square footage.
Make sure all units are in feet: 6in12=. 5ft{\displaystyle {\frac {6in}{12}}=. 5ft} Multiply square footage by height: 100∗. 5=50{\displaystyle 100*. 5=50} Express answer in cubic feet You must purchase at least 50ft3{\displaystyle 50ft^{3}} of soil to fill your garden.
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 is 566. 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.

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.
