12 x 12 x 6 = 864 cubic feet.
864 = 6 x 8 x 18
864 cfm (cubic feet per minute) represents air flow in terms of volume of air measured in cubic feet, whereas 864 cmh (cubic meters per hour) is air flow measured in cubic meters over an hour. The conversion factor from cfm to cmh is approximately 1 cfm = 1.7 cmh, so 864 cfm would have more air flow than 864 cmh due to the difference in volume units.
cubic feet is a volume unit not area unit but anyway the result is: 768 cubic feet = 28.44 cubic yards
There are 12 inches in one foot. Therefore, 864 inches is equal to 864/12 = 72 feet.
24 x 36 = 864 square feet.
1/2 cubic foot equals 864 cubic inches.
1/2 cubic foot is 864 cubic inches.
There are 304.8 millimetres in one foot. Therefore, rounded to two decimal places, 864 millimetres is equal to 864/304.8 = 2.83 feet.
There are: 24 feet times 36 feet = 864 square feet
A cubic foot measures 12" x 12" x 12", so it contains 1728 cubic inches. Therefore, half a cubic foot is 1728/2, or 864 cubic inches. But the implication of the original question is PROBABLY meant to be -- what are the dimensions of a cube if its volume is one-half of a cubic foot? The exact answer, expressed in inches, is: (the cube root of 864) x (the cube root of 864) x (the cube root of 864); or, for practical purposes, just a little larger than 9.5" x 9.5" x 9.5".
