# A cuboidal water tank is 6 m long,

Question. A cuboidal water tank is $6 \mathrm{~m}$ long, $5 \mathrm{~m}$ wide and $4.5 \mathrm{~m}$ deep. How many litres of water can it hold? $\left(1 \mathrm{~m}^{3}=1000 /\right)$

Solution:

The given cuboidal water tank has its length $(l)$ as $6 \mathrm{~m}$, breadth $(b)$ as $5 \mathrm{~m}$, and height $(h)$ as $4.5 \mathrm{~m}$.

Volume of tank $=l \times b \times h$

$=(6 \times 5 \times 4.5) \mathrm{m}^{3}=135 \mathrm{~m}^{3}$

Amount of water that 1 m3 volume can hold = 1000 litres

Amount of water that $135 \mathrm{~m}^{3}$ volume can hold $=(135 \times 1000)$ litres

= 135000 litres

Therefore, such tank can hold up to 135000 litres of water.
