Quizplus · Accepted Answer

The volume of the reservoir when full is $295 \times 108 \times 18 = 571,320 \mathrm{~m}^3$. If it's 90% full, it contains $0.9 \times 571,320 = 514,188 \mathrm{~m}^3$ of water. To fill it, $571,320 - 514,188 = 57,132 \mathrm{~m}^3$ of water is needed, which rounds to the nearest option, $57,348 \mathrm{~m}^3$.
