There is no such unit as "cubic square feet".
If you want to calculate the cubic feet of volume in a room, multiply the room's length (in feet)
by its width (in feet), and then multiply that result by the room's height (in feet).

The formula for Cubic Feet is: Length × Width × Height. For example, a 600 square foot room with a 10 foot ceiling would be 6000 cubic feet.
This room is a rectangular prism. The equation for a rectangular prism to find the volume is the LxWxH=V. 50x28x15=1400x15=21000 cubic feet The number of cubic feet in this room is 21000 cubic feet.
Well, honey, a room that's 450 cubic feet could be about 15 feet long by 10 feet wide by 3 feet high. But hey, who am I to judge? You could also have a room that's 5 feet long by 5 feet wide by 18 feet high. As long as it adds up to 450 cubic feet, you're good to go!
To find the square feet of a room, multiply the length times the width. 12 feet X 12 feet = 144 square feet.
To find the square footage of a room, you simply multiply the length of the room (in feet) by the width of the room (in feet). The answer is the square footage of the room (assuming the sides opposite each or are equal in length)
