Question

State whether true or false.

The internal length, breadth and height of a closed box are 1 m, 80 cm and 25 cm respectively. If its sides are made of 2.5 cm thick wood; then the capacity of the box is $0.2m^3$.

• A. True
• B. False

Answer 1

The correct option is A True

Given,
The internal length, breadth and height of a closed box are $1m=100cm,80cm$ and $25cm$, respectively.
As its sides are made of $2.5cm$, the external length, breadth and
height of the closed box are $100+2\left(2.5\right)=105cm,80+2\left(2.5\right)=85cm$ and $25+2\left(2.5\right)=30cm$, respectively.
Capacity of the box which is cuboidal in shape $=105\times 85\times 30=267750c{m}^3=0.2m^3$
