Answer 1

First find the external lbh of box then internal lbh of box and at last minus it u will get the ans

Answer 2

The capacity of the box is 39600 cubic cm and the volume of wood used to make the box is 25920 cubic cm

Step-by-step explanation:

Thickness of wood = 3 cm

External length = 56 cm

External breadth = 39 cm

External Height = 30 cm

Internal length = 56-(3+3)= 50 cm

Internal breadth= 39-(3+3)= 33 cm

Internal Height=30-(3+3)= 24 cm

Capacity of box = $50 \times 33 \times 24 =39600 cm^3$

Volume of wood used = External volume - Internal volume =$(56 \times 39 \times 30)-(50 \times 33 \times 24)=25920 cm^3$

Hence the capacity of the box is 39600 cubic cm and the volume of wood used to make the box is 25920 cubic cm
