A hole 40 inches deep by 12 inches wide has a volume of: 2.62 cubic feet.
1.963 cubic feet
The volume of an area 24 feet round and 45 inches deep is: 1,700 cubic feet.
You would multiply out the two numbers to get 2835 cubic inches. Divide that by 1728 to get 1.64 cubic feet.
Three acres three inches deep is 403.33 cubic yards.
I say 1.09 cu ft.
328,320 cubic inches

To determine the volume of an 11-inch round pan that is 3 inches deep, use the formula for the volume of a cylinder: V = πr²h. The radius (r) is half of the diameter, so for an 11-inch pan, r is 5.5 inches. Plugging in the values, the volume is approximately 95.03 cubic inches. Since 1 cup is about 14.44 cubic inches, this pan can hold roughly 6.6 cups.
About 8.5 (Pi*(6/12)^2*290)/27
The mattress would have a total area of roughly 1.04 cubic yards. However, a cubic yard is one yard long by one yard wide by one yard deep. The mattress is only 8 inches deep, not enough to equal a yard, so it really does not have any one area that is a cubic yard in size.
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
cylinder 18 feet diameter x 1.5 feet deep volume = 381 cubic feet
