Square feet is two-dimensional. A flat area 20 feet wide by 10 feet deep is 200 square feet. But cubic feet is three-dimensional. Think of a box 12" wide by 12" deep by 12" high. That's a cubic foot. To determine cubic feet, take the width x depth x height (in inches) and divide by 1728.
It would help to know what units of measurement are used for 20*20*8. Are they feet or yards or metres or something else?But in the US, most rooms are measured in feet, and 8 feet tall is about right for a room in a house, so (20 ft)*(20 ft)*(8 ft) = 3200 cubic feet.
To convert the measurements to meters and calculate the volume of the room in cubic meters, we have: 10.0 ft = 3.05 m, 11.0 ft = 3.35 m, and 8.00 ft = 2.44 m. The volume of the room would be 3.05 m x 3.35 m x 2.44 m = 24.37 cubic meters. Since 1 cubic meter is equal to 1000 liters, the room would contain 24.37 x 1000 = 24,370 liters of air.
1 cu ft = 0.037037 cu yeard
7.481 gal - 1 cu ft; 17,000 gal = 2,272.42 cu ft
To find the cubic volume, multiply the floor space by the ceiling height: 3500 sq ft x 9 ft = 31,500 cubic ft.
3 measurements are needed to calculate volume. IF your room has an 8 ft ceiling then it is approximately 800 cu ft.
16ft x 12½ft for example
2 cubic ft to 6 cubic ft is a 200% increase.
A typical room can have 5 to 6 times more volume than the 200 cu.ft given. Example: 15 ft long x 10 ft wide x 8 ft high = 15*10*8 = 1200 cu.ft.
That is 3,000 cubic ft.
How many cubic ft.in a room 12 ft.by 10.6 ft. by 8 ft. high?
100 cu ft × 2 = 200 cu ft.
You must know the height of the room to determine this. If the room has a flat 8 foot high ceiling there are 1664 cubic feet of volume in the room
That is 1,152 cubic ft.
200 cubic feet.
1000L equates to about 35.31 cubic feet.
Volume = 301592894.7 cubic feet
