Question

a closed box is made of 2 cm thick wood with external dimension 84* cm*75*64cm find the volume wood to Requird box

Answer 1

volume of box with wood=84× 75× 64
=403200cubic cm
volume of wood=403200-340800
=62400cm^3

Answer 2

Volume of wood is 62400 cubic cm

Step-by-step explanation:

External length of box = 84 cm

External Breath of box = 75 cm

External Height of box = 64 cm

Thickness = 2 cm

Internal length of box = 84cm-(2+2)cm = 80 cm

Internal Breath of box = 75 cm -(2+2)cm = 71 cm

Internal Height of box = 64 cm-(2+2)cm = 60 cm

Volume of box = $Length \times Breadth \times Height$

Volume of wood required = External volume - Internal volume

Volume of wood required =$(84 \times 75 \times 64 )-(80 \times 71 \times 60)$

Volume of wood required =$62400$

Hence volume of wood is 62400 cubic cm
