Jean poured water into a rectangular tank at the right until is was 2/3 full. Then she poured some of the water out until it was 2/5 full. How much water did she pour out of the tank? Give your answer in millimeters.

The amount of water she poured out of the tank is 27,000 m³.

Step-by-step explanation:

To answer the question, we take the dimensions of the tank as

Width = 0.5 m

Length = 0.2 m

Height = 1 m

Therefore, if the tank was was filled to 2/3 of the volume, then we have

Volume of water in the tank = 2/3 × 0.5 m × 0.2 m × 1 m

= 0.067 m³

She then poured out water until the tank was 2/5 full. That is

2/5 × 0.5 m × 0.2 m × 1 m = 0.04 m³

Therefore, the amount of water she poured out of the tank is

0.067 m³ - 0.04 m³ = 0.027 m³

However, 1 m³ = 1 × 10⁶ mm³

Therefore 0.027 m³ = 27,000 mm³

The amount of water she poured out of the tank = 27,000 m³.
