A foot is a measure of distance while a cubic foot is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
36-ft x 24-ft x 20-ft = 17,280 cubic feet
100 cu ft × 2 = 200 cu ft.
3 baloons per 9 sq ft
If the dimensions given are inches, there are 49.11 cu. ft. If they are in feet there are 84,864 cu. ft.
sq feet to sq yards cu ft to cu yards you need depth added to your sq ft to get cu ft such as 70 sq ft x 4 in deep = 23.33 cu ft =.086 cu yd
27 cu. ft. = 1 cu. yd.
5 cu/yrds x 27 cu/ft = 135 cu/ft
36 ft
51840 cu ft
797 cu yards = 797 * 33 cu feet = 21519 cu ft.
27 cu ft = 1 cu yd
55.8 cu ft = 1.581 cu metres.
