Question

a closed box is made of wood 2cm thick and its length breadth and height externally are 80cm 60cm and 50cm find the volume of wood​

Answer 1

Answer:

volume of wood=80×60×50=240,000‬cm

3

Dimensions of inner wood because to calculate the volume of wood required we have to subtract the inner dimensions from outer dimensions.

Thickness of wood=2 cm

Inner dimension=(80−4)×(60−4)×(50−4)

=76×56×46=1,95,776 cm

volume of wood=2,40,000‬−1,95,776=44,224 cm
