Since a foot is 12 inches, and a cubic foot is 12 inches on each edge, there are 12 x 12 x 12 = 1728 cubic inches in a cubic foot. This problem uses the volume formula: V = lwh, where l is length, w is width, and h is height.
The amount that a cubic foot of water weighs depends on the temperature of the water. At 70 degrees F. a cubic foot of water weighs 62.50 pounds.
It's the same amount as the amount of regular inches in a regular foot; 12.A cubic foot contains 1,728 cubic inches.
27 cubic feet = 1 cubic yard Volume = (length) x (width) x (depth) = 10 x 4 x 1 = 40 cubic feet = 1.48 cubic yards (rounded)

There are 1,728 cubic inches per cubic foot.
Because the unit is in cubic feet, not feet, you can't just divide by twelve (because there are twelve inches in a foot.) You have to cube the amount of inches in a foot, (being twelve,) to find out how many cubic inches are in one foot. Twelve cubed is 1,728, so there are 1,728 cubic inches in a foot. From there you just multiply by three, giving you 5,184.
49'x22'x3"(or.33) divid that by 27 and then multiply by 1.5 for tons of rock needed.length times width times depth divided by cubic feet then multiply by the aproximate tons per cubic yards gives you how much rock is needed.
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
