Q : 2    A cuboidal water tank is 6 m long, 5 m wide and $\small 4.5\hspace{1mm}m$ deep. How many litres of water can it hold? ($\small 1\hspace{1mm}m^3=1000\hspace{1mm}l$)

Given,

Dimensions of the cuboidal water tank = $6\ m \times5\ m\times 4.5\ m$

We know,

Volume of a cuboid = $l\times b \times h$

$\small \therefore$ Volume of the water tank = $\small (6 \times5\times 4.5)\ m^3 = 135\ m^3$

We know,

$\small 1\hspace{1mm}m^3=1000\hspace{1mm}l$

$\small \therefore$ Volume of water the tank can hold = $\small (135\times1000) = 135000\ litres$
