Question

A construction crew is building a swimming pool that is 6 feet wide, 20 feet long, and 8 feet deep. Once everything is complete, they fill the pool until it is 7/8 full. What was the volume of the water in the pool?

Answer 1

To find the volume, you do length times width times height. 
So you do 6*20*8
The answer is 960ft cubed. 
However, you have to fill the pool 7/8 full.
960*7/8=840.875 ft cubed
