Question

A boat having a length 3m and breadth 2m is floating on a

lake. The boat sinks by 1cm when a man gets on it. The mass
of the man is:
​

Answer 1

60 kg

Step-by-step explanation:

The man's weight is equal to the weight of the water he displaces.

mg = ρVg

m = ρV

m = (1000 kg/m³) (3 m × 2 m × 0.01 m)

m = 60 kg

The man's mass is 60 kg.
