Let's go swimming!

A swimming pool is 50.0 ft wide, 78.0 ft long, 3.5 ft deep at one end and 8.5 ft deep at the other end.

How many cubic feet of water can it hold?

(The slope on the bottom is assumed to be constant.)

While your reasoning, calculations, and answer were correct for figuring the volume of the swimming pool, you did err a bit by calling the shape of the side of the pool a "parallelogram". It is in reality a "trapezoid". A parallelogram is a quadrilateral with both pairs of opposite sides parallel. A trapezoid is a quadrilateral with exactly one pair of sides parallel, in our case, this is the shape of the figure (and the side of the pool) shown in your answer.
