Given :

A boat having a length of 3 metre and breadth 2 metre is floating on a lake. The boat sinks by 1 cm when a man gets on it.

To find :

The mass of the man is

Solution :

Volume of water displaced

➵ v = 3m x 2m x (1/100)m

➵ v = (6/100) m³

mass of man = mass of water displaced

➵ m = vp

➵ (6/100m³) (1000kg/m³)

➵ 60 kg

The mass of the man is 60 kg

Extra information :

Cube

  • V = s³

Right Rectangular Prism

  • V = LWH

Prism or Cylinder

  • V = Ah

Pyramid or Cone

  • V = ⅓Ah

Sphere

  • V= 4/3πr³

Answer:

Given

\leadsto A boat having a length of 3m and breadth of 2m is floating on a lake.

\leadsto The boat sinks by 1cm when a man gets on it.

To Find

\leadsto What is the mass of the man.

Solution

Length of a boat is 3m.

Breadth of a boat is 2m.

The boat sinks depth by 1cm or 1-² cm

\bold{\large{\fbox{\color{blue} {Mass of man = Volume of water display × density of water}}}}

\implies (3×2×10-²)m³ × (10³) kg/m³

\implies 3 × 2 × 10 kg

\implies 60 kg

The mass of man is 60 kg.
