7.54 cubic meters
The floor is 4 times 288 times 384 cubic inches, or 442,368 cubic inches. 1 inch = 2.54 centimeters. Thus, 1 cubic inch = 2.54 times 2.54 times 2.54 cubic centimeters, or 16.387064 cubic centimeters. So 442,368 cubic inches is 7,249,112.727552 cubic centimeters. Each cubic centimeter is 0.000001 cubic meters (1,000,000 cubic centimeters = 1 cubic meter). So the floor is 7.249112727552 cubic meters. You can essentially call this 7.25 cubic meters. You can also determine from this that a cubic inch is 0.0000016387064 cubic meters, which can be used as a shortcut.
Approx 70.6 square feet.
This question can not be answered because square feet are a measure of area and a cubic meter is a measure of volume.
Apples and oranges. Without knowing how thick the 450 sq. ft. area is or how thick you want it to be you can't convert to cubic yards. A cubic yard has 27 cubic feet. One square foot 3 inches thick would be 1/4 cubic feet. 4 sq. ft. 3 inches thick would be 1 cubic foot. 450 sq. ft. 3 inches thick is 112 1/2 cubic feet or just a bit over 4 cubic yards. 450 sq. ft. 4 inches thick is 150 cubic feet or 5 1/2 cubic yards.
4 inches = 0.1016 metres. So volume = pi*r2*h = pi*(17/2)2*0.1016 = 23.1 cubic metres (approx)
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
A 9x9 foot slab 4 inches thick requires a minimum of 1 cubic yard. If you go to 6 inches thick you will need 1.5 cubic yards.
You will need 5.5 40kg bags for this floor. This allows for a typical waste factor of 5%
1.5 meters = 59.055 inches.
A cubic metre would make a 25mm thick cuboid covering an area of 40 square metres.
It is about 5 inches ^^
As far as I know; to equal ft. and inches (366sq. ft. and 6 inches ) if you convert this iti is 366 divided in half to give you a 12 inch depth =183 cubic ft and divide by 3 to get cubic yards = 61 cubic yards
