Question

An Olympic-size pool is 50.0 m long ang 25.0 m wide. How many gallons of water (density = 1.0 g/mL) are needed to fill the pool to an average depth of 4.8 ft?

Answer 1

Given that,

Length =50.0 m

Wide = 25.0 m

Depth = 4.8 ft = 4.8  0.3048 = 1.46 m

Volume of the pool = 50 m  25 m  = 1828.8 

We know that,

 1.0  = 264.17 gal

Therefore, the amount of water needed to fill the pool = 1828.8   = 483114.09 gal.
