How many gallons are in a 27x4 pool?

Answer 1

In order to find out how many gallons there are in this pool (and for other questions similar to this) you need to say how deep it is. Since a pool is 3-dimensional, you need a third dimension which is height. Then you can find the volume and convert that to gallons.

=========================================

Another contributor tried to help:

-- If the bottom of the pool is 27-ft by 4-ft and level, then

its capacity 807.9 gallons (rounded) for every inch of depth.

-- We have no way of knowing how much water is in it.

It could be empty and bone dry for all we know.
