That is 187.5 cubic ft.
3 measurements are needed to calculate volume. IF your room has an 8 ft ceiling then it is approximately 800 cu ft.
That is 355.25 cubic ft.
81 cubic feet Why? 3 X 3 = 9 (9)^2 = 81
60 cubic feet
None, to work out cubic feet you need three dimensions, 3 feet x 20 feet is 60 square feet, to get to cubic feet you need another dimension.
12.36 ft^3
Volume of sand required = 6 ft * 5 ft * 1 ft = 30 cubic feet. A bag = 3 cubic feet so number of bags required = 30/3 = 10 bags.Volume of sand required = 6 ft * 5 ft * 1 ft = 30 cubic feet. A bag = 3 cubic feet so number of bags required = 30/3 = 10 bags.Volume of sand required = 6 ft * 5 ft * 1 ft = 30 cubic feet.

Square feet is 2-dimensional while cubic feet is 3-dimensional, so they cannot convert.
To calculate the volume of concrete needed for the sidewalk, first convert the 4 inches thickness to feet (4 inches = 1/3 feet). Then, multiply the length (40 ft) by the width (3 ft) by the thickness in feet (1/3 ft) to get the total volume in cubic feet. This comes out to be 40 ft * 3 ft * 1/3 ft = 40 cubic feet of concrete needed for the sidewalk.
22 x 30 x 3.25 = 2145 cubic feet (2145 ft3)
Do the math...1 yd=3 ft. So, 3'x3'x3'=27 cu ft (or 1 cu yd). 27 cu ft x 12 cu yd=324 cu ft!
