How to calculate cubic feet ?
Calculating the cubic feet of a space requires multiplying the area of the bottom times the average height. You get the bottom area by multiplying the length times the width. Remember, to get cubic feet, you need all your measurements in feet to start with.
Here is your formula:
VOLUME (in cubic feet) = Length (in feet) X Width (in feet) X Height (in feet)
If it's a rectangular room you're working with, it is all straightforward. If there are irregular walls, it may be necessary to divide up the room into rectangular sections and then add together their individual volumes. If the ceiling is sloped, you need to use the height that has the same ceiling area above it as below it. Good luck! Truly.
