Answer 1

Answer:

1288 cubic cm of wood are there in  a closed box  and the cost of wood required to make the box is Rs.5796

Step-by-step explanation:

Length of box = 14 cm

Breadth of box = 11 cm

Height of box = 12 cm

The thickness of wood = 2 cm

Inner length = 14-(2+2)=10

Inner Breadth =11-(2+2)=7

Inner Height=12-(2+2)=8

The volume of wood = Outer volume - Inner volume

 The volume of wood =  

The volume of wood =

Cost of 1 cubic cm wood = Rs.4.50

Cost of 1288 cubic cm wood =  

Hence 1288 cubic cm of wood are there in a closed box  and the cost of wood required to make the box is Rs.5796
