You missed out one vital statistic... the height of the room !
1100 cubic feet
The volume of such a room is 480 cubic feet.
960 cubic feet
8 feet x 10 feet x 12 feet = 960 cubic feet
3 measurements are needed to calculate volume. IF your room has an 8 ft ceiling then it is approximately 800 cu ft.
10X10X8=800
10 cubic feet is 10 cubic feet regardless of the system. A square foot is 12x12x12 inches. It does not change.
That is 250 cubic ft.
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.
Volume = length * width * height. (The * is a 'multiply' sign). So, 16.2 feet* 9.8 feet* 8 feet = the answer in cubic feet. This is how to solve the problem. If you need a calculator, windows has one (or Google will act as one.)
8640ubic feet
The volume of a 10x10 square foot room is 1,000 cubic feet. To calculate this, you multiply the length (10 feet) by the width (10 feet) and the height (assuming a standard 8-foot ceiling) to get the total cubic footage.
