A large rectangular swimming pool is 1,000 feet long 100 feet wide and 10 feet deep how much water does the pool hold?

Ymorist [56]

ANSWER

The swimming pool can hold 1,000,000 cubic feet of water.

EXPLANATION

The capacity of water the pool holds is the volume of water in the swimming pool.

The swimming pool is rectangular, therefore its volume can be calculated using the formula,

$V = l \times w \times h$

where l=1000ft is the length, w=100ft is the width and h=10ft is the height of the pool.

We substitute all these values into the formula to get:

$V = 1000 \times 100 \times 10 = 1000000 {ft}^{3}$

The swimming pool can hold 1,000,000 cubic feet of water.
