Answer 2

The cost of the wood required to make the box is Rs.829.668 and The volume of the wood is 97.608 cubic cm.

Step-by-step explanation:

Length of box = 20 cm

Breadth of box = 12 cm

Height of box = 8 cm

The thickness of the word used to make the box is 10 mm = 0.1 cm

Inner length = 20-(0.1+0.1)=19.8

Inner breadth = 12-(0.1+0.1)=11.8

Inner height = 8-(0.1+0.1)=7.8

Volume of wood = Outer volume - Inner volume

Volume of wood =$(20 \times 12 \times 8)-(19.8 \times 11.8 \times 7.8)$

Volume of wood =$97.608 cm^3$

1.The volume of the wood is 97.608 cubic cm.

Cost of 1 cm cube wood = Rs.8.5

Cost of 97.608 cm cube wood = $97.608 \times 8.5=Rs.829.668$

Hence the cost of the wood required to make the box is Rs.829.668 and The volume of the wood is 97.608 cubic cm.
