A water tank of height \(\frac{1}{2}\) m has a square base of side \(1\frac{1}{2}\) m. lf it is filled with water from a water tanker holding 1500 litres, how many litres of water are left in the water tanker? [1000 litres = 1m\(^3\)]
- 37.5litres
-
375 litres
- 3750 litres
- 37500 litres
- 375000 litres
The correct answer is: B
Explanation
Volume of water taken by the tank = \(\frac{3}{2} \times \frac{3}{2} \times \frac{1}{2}\)
= \(\frac{9}{8} m^3\)
= \(\frac{9}{8} \times 1000\)
= 1125 litres
\(\therefore\) Water left = (1500 - 1125) litres
= 375 litres.
