### How many gallons are in a pool 18 feet x 38 feet that is 5 feet in the deep end and 3 feet in the shallow end?

That is not enough information to tell you how many gallons are in the pool. The length/width of the deep/shallow end individually are needed for an approximation. I can give you the min and max gallons of the pool though. A gallon is 231/1728 cu. ft. Assuming the whole pool was 5 ft deep: 18 ft X 38 ft X 5 ft = 3420 cu. ft = 457.1875 gallons maximum. Assuming the whole pool was…

### How much dirt is in a 5 feet deep and 3 feet wide hole?

As it is a hole, there is no dirt in it. However, assuming you have a cylindrical hole 3 ft wide, the volume of dirt removed to make the hole is: volume = π x radius2 x depth = π x (3/2)2 x 5 cu ft = 45π/4 cu ft ≈35.34 cu ft If your hole is a cuboid, that is it is 3 ft x 3ft by 5 ft deep, then the volume of…
