Question

A cuboid tank measuring 15m long,10 m broad and 4cm deep is full of water .The water is pumped into anathor tank which is 20m long and 15 m broad .Find the depth of the water in a new tank.

Answer 1

correction: length , breadth, and depth of cubiod water tank are 15 m, 10 m, and 4 m.

volume of first cuboid tank

= length × breadth × depth

= 15 × 10 × 4 = 600 m^2

given, length of second tank 20 m ,and breadth = 15 m, then depth = ?

since , the water is pumped into another tank

thus,volume of water in second tank will be equal to the volume of water which was in first tank.

600 = 20 × 15 × depth

depth = 600 ÷ 300 = 2 m

therefore,

depth of the water in another tank = 2 m

Answer : depth = 2 m

Answer 2

Step-by-step explanation:

Volume of old tank = l×b×h ( volume of cuboid)

= 15 × 10 × 4

= 600

= 600 liters of water

The water is pumped into another tank

= Volume of new tank = 20 × 15 × h

= 600 = 20 × 15 ×h

= h = 600 / 20 × 15

= h = 2

Depth of another tank is 2m
