Question

a pool is 55.3 m long and 44.9 m wide. if the average depth of water is 5.70ft, what is the mass (in kg) of water in the pool? Enter your answer in scientific notation.

Answer 1

4.31×10⁶ kg

Step-by-step explanation:

The volume of water in the pool is ...

V = LWD

V = (55.3 m)(44.9 m)(5.70 ft)(0.3048 m/ft) = 4313.8127592 m³

We assume you want use 1000 kg/m³ as the density of water, so the mass of this water is ...

M = (4313.8127592 m³)(1000 kg/m³) ≈ 4.31×10⁶ kg
