Mensuration Practice Test 5

Volume of water in the tank = l × b × h
= 150 × 100 × 3
= 45,000 ${\mathit{m}}^3$
Volume of water in the tank
= (2 dm)× (1.5 dm)× (15 km/hour)× Time
45000 = $\left(\frac{2}{10}\mathit{m}\right)\left(\frac{1.5}{10}\mathit{m}\right)\left(\frac{15\times 5}{18}\mathit{m}∕\mathit{s}\mathit{e}\mathit{c}\right)$ × Time
Time = 45,000 × $\frac{10}{2}\times \frac{10}{1.5}\times \frac{1}{15}\times \frac{18}{5}$
Time = 3,60,000 seconds
Time = 100 hours
