waecmaths question:
The dimension of a water are 13cm, 10cm, and 70cm . If it is half-filled with water. Calculate the volume of water in litres.
Option A:
4.55 litres
Option B:
7.50litres
Option C:
8.10 litres
Option D:
9.55 litres
waecmaths solution:
$\begin{align} & Volume=length\times breath\times height=lbh \\ & V=13cm\times 10cm\times 70cm=9100c{{m}^{3}} \\ & \text{Since the tank is half filled, the volume will be } \\ & \frac{V}{2}=\frac{9100c{{m}^{3}}}{2}=4550c{{m}^{3}} \\ & 1litres=1000c{{m}^{3}} \\ & 4550c{{m}^{3}}=4.55litres \\\end{align}$
