Question

A cubical closed wooden box of internal dimensions 1m×1m×1m , made up of 5cm thick wood.Find the volume of wood required to make the box and also find the cost of wood at the rate of ₹18,600 per cubic metre. ​

Answer 1

Step-by-step explanation:

Height =1m+5cm=1.05

Volume of the wood =outer-inner volume

=1.1*1.1*1.05-1*1*1

=1.2705-1.0000

=0.2705m3

Cost of wood 1m3=Rs9600

So,cost of 0.2705m3=9600*0.2705 =Rs2596.80
