Question

A cuboidal shaped milk-tank measures 2 m x 50 cm x 40 cm. This tank is completely filled with milk. How many 200 ml milk packets can be filled with this milk?

Answer 1

Length of the cuboidal tank = 2 m.
Breadth of the cuboidal tank = 50 cm. = 0.5 m.
Height of the cuboidal tank = 40 cm. = 0.4 m.
∴ Volume of the cuboidal tank = 2 × 0.5 × 0.4
= 1 × 0.4
= 0.4 m³
= 400 litres. [∵ 1 m³ = 1000 L]
= 400 × 10³ ml. [∵ 1 L = 1000 mL]

∴ No. of packets of the 200 mL = 400 × 10³/200
= 2000
Hence, the number of packets is 2000.

Hope it helps.

Answer 2

Acc to the ques, a cuboidal shaped milk-tank measures 2 m x 50 cm x 40 cm.

It is also said that the tank is completely filled with milk.

Volume of the milk-tank = 2 x 0.5 x 0.4 = 0.4m³.

We know, 1m³ = 1000 L.

or, 0.4m³ = 400 L = 400 x 1000 = 400000 ml.

Number of 200 ml milk packets can be filled with this milk = 400000/200 = 2000 packets.
