Anu bought an air cooler as shown below. its water tank is in the shape of a cuboid and can take 40 litres of water. its dimensions are 50cmx 20cm. what will be the length of the water tank?

Length of water tank is 40 cm

Given that;

Capacity of tank = 40 liters

Dimensions of tank = 50cm × 20cm

Find:

Length of water tank

Computation:

Capacity of tank = 40 liters

Capacity of tank = 40 × 1000

Capacity of tank = 40,000 cm³

Length of water tank = 40,000 / [50cm × 20cm]

Length of water tank = 40,000 / 1,000

Length of water tank = 40 cm

40 cm

Step-by-step explanation:

Using the conversion

1 litre = 1000 cm³, then

40 litres = 40 × 1000 = 40000 cm³

The volume ( V) of a cuboid is

V = lbh ( divide both sides by bh )

l = = = = 40 cm
