Given
External dimension of box
L=80cm
B=75cm
H=60cm
Thickness of walls=2cm
So internal dimensions of box would be
l=80-(2+2)=76cm
b=75-(2+2)=71cm
h=60-(2+2)=56cm
Volume of wood required = volume of box with external dimensions - volume of box with inner dimensions
Volume of box with external dimensions =L X B X H
=80X75X60
=360000cm³
Volume of box with inner dimensions =lxbxh
=76x71x56
=302176cm³
Volume of wood required =360000-302176
=57824cm³
This is ur ans hope it will help you in case of any doubt comment below
