Question

A wooden box has external dimensions of 40 cm by 34 cm by 30 cm .if the wood is 1 cm .how many cm3 of wood are there in it?

Answer 1

Given:

Outer length(L) = 40cm
Outer breadth(B) = 34cm
Outer height(H) = 30 cm

Thickness= 1 cm

Volume of the box= L× B×H

Outer volume of the box = 40 cm × 34 cm × 30 cm

Outer volume of the box = 40800 cm³


Thickness = 1 cm


Inner length (l)= 40 cm -(2×1)=40-2 = 38 cm
Inner breadth (b)= 34 cm - (2×1)= 32 cm
Inner height(h) = 30 cm -(2× 1)= 28 cm

Inner volume of the box = 38 cm × 32cm × 28 cm


Inner volume of the box = 34048 cm³


Volume of wood =outer volume of box - Inner volume of box

= 40800 -34048 = 6752 cm³

Hence, the volume of wood = 6752 cm³
