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\(^3\)]
A. 37.5litres B. 375 litres C. 3750 litres D. 37500 litres E. 375000 litres
Correct Answer: 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.
