Question

a closed box made of wood which is 3 centimetre thick its external Length breadth height are 56 centimetre 39 centimetre and 30 centimetre respectively find the capacity of the box also find the volume of wood used to make a box

Answer 1

We know, box is in cuboid shape.

Given, [box is opened from one end]

External Dimensions (56 cm x 39 cm x 30 cm)

Thickness of the wood = 3cm 

∴Internal dimensions = 50 cm x 33 cm x 27 cm[30-3] 

The capacity of box = lbh

                                = 50 x 33 x 27

                                = 44550 cm³

Volume of wood = external volume - internal volume

                          = [(50 x 33 x 30) - (50 x 33 x 27)]

                          = [65520-44550]

                          = 20970 cm³
