For rain water harvesting a tank of length 10 m, breadth 6 m and depth

1.	For rain water harvesting a tank of length 10 m, breadth 6 m and depth 3 m is built. What is the capacity of the tank? How many litre of water can it hold?
Answer» Given: For a cuboidal tank, Length (l) = 10 m, breadth (b) = 6 m, depth (h) = 3 m To find: Capacity of the tank and litre of water tank can hold. i. l = 10m = 10 x 100 …[∵ 1m = 100cm] = 1000 cm, b = 6 m = 6 x 100 = 600 cm, h = 3 m = 3 x 100 = 300 cm Volume of the tank = l x b x h = 1000 x 600 x 300 = 18,00,00,000 cc ii. Capacity of the tank = Volume of the tank = 18,00,00,000 cc = 18,00,00,000/1000 …[∵ 1 litre =1000 cc] = 1,80,000 litre ∴ The capacity of the tank is 18,00,00,000 cc and it can hold 1,80,000 litre of water.

Given: For a cuboidal tank,

Length (l) = 10 m, breadth (b) = 6 m, depth (h) = 3 m

To find: Capacity of the tank and litre of water tank can hold.

i. l = 10m = 10 x 100 …[∵ 1m = 100cm] = 1000 cm,

b = 6 m = 6 x 100 = 600 cm,

h = 3 m = 3 x 100 = 300 cm

Volume of the tank = l x b x h

= 1000 x 600 x 300

= 18,00,00,000 cc

ii. Capacity of the tank = Volume of the tank

= 18,00,00,000 cc = 18,00,00,000/1000 …[∵ 1 litre =1000 cc] = 1,80,000 litre

∴ The capacity of the tank is 18,00,00,000 cc and it can hold 1,80,000 litre of water.
