Suppose an Olympic-size swimming pool in the shape of a rectangular solid has a volume of 4000 cubic meters, a length of 80 meters, and a width of 20 meters. What is the depth of the pool? Round your answer to one decimal place.

A) 1.5 meters
B) 2.5 meters
C) 4 meters
D) 6 meters
E) 3.5 meters

Answer :

B

v=l•w•h
4000=80•20•h
4000=1600•h
h=2.5 m

To find the depth of the swimming pool, use the formula for the volume of a rectangular solid and substitute the given values to calculate the depth as 2.5 meters.

The depth of the Olympic-size swimming pool can be calculated using its volume, length, and width.

First, use the formula for the volume of a rectangular solid:

Volume = Length x Width x Depth

4000 = 80 x 20 x Depth

Depth = 4000 / (80 x 20) = 2.5 meters

Depth = 2.5 meters
