To convert square feet to cubic feet, you need to know the height or depth of the space. If the height is 1 foot, then 400 square feet would equal 400 cubic feet. However, if the height is different, you would need to multiply the square footage by the height in feet to get the cubic footage. For example, if the height is 10 feet, then 400 square feet would equal 4000 cubic feet.
