Please help with Volume

Archy [21]

Given:

Length of the cuboid tank = 4 m

Breadth = 2.5 m

Height = 2.4 m

One third of the tank is filled with water.

1 cubic meter = 1000 liters.

To find:

The quantity of the water in the tank.

Solution:

Volume of a cuboid is:

$V=l\times b\times h$

Where, l is length, b is breadth and h is the height.

The volume of the tank is :

$V=4\times 2.5\times 2.4$

$V=24$

Volume of tank is 24 cubic meter.

One third of the tank is filled with water. So, the volume of the water is

$\dfrac{24}{3}=8$

The volume of water is 8 cubic meters.

We have,

1 cubic meter = 1000 liters.

8 cubic meter = 8000 liters.

Therefore, the quantity of the water in the tank is 8000 liters.
