Slightly less than 1. 5x10 is 50 square feet. If the pad was 6 inches thick that would equal 25 cubic feet. There are 27 cubic feet in 1 cubic yard.
9.3 cubic yards of cement is required for this slab.
Yards are for measuring length not volume. Cubic yards required will be as follows: 1 cubic yard = 3 feet x 3 feet x 3 feet = 27 cubic feet Your concrete pad is 30ft x 40ft x 0.3333ft (4 inches assumed) = 400 cubic feet 400 divided by 27 = 14.8148 cubic yards required

50x100x4 = 20,000 cubic inches36 inches in a yard20,000/36 = 555 5/9 cubic yards.
It is about 166.67 cubic feet and you will need just over 6.17 cubic yards of concrete.
Convert the measurement in square feet to square yards and the thickness in inches to yards. 3 feet = 1 yard 9 square feet = 1 square yard. : 1100 square feet = 1100/9 = 122.2222 sq yards 36 inches = 1 yard 5 inches = 5/36 = 0.13888 yards. The amount of concrete required = 122.2222 x 0.13888 = 16.975 cubic yards In practice, an order would be sent for 17 cubic yards of concrete.
An area 20ft x 34' is 680 square feet. 4 inches is 1/3 of a foot so cubic feet required is 680 x 1/3 = 226.7 cubic feet. There are 3x3x3 = 27 cubic ft in a cubic yard. Therefore cubic yards required = 226.7/27 = 8.4 cubic yards
1.7572 cubic yards
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
Not square yards, but Approx. 5.24 cubic yards 54'2" = 650" x 7'10" = 94" x 4" = 4" = 244,400 cubic inches / 46,656 cubic inches = 1 cubic yard (36" x 36" x 36")= 5.24 cubic yards
