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.

4.31*10⁶ kg

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
