Question

A closed box is cuboidal in shape with dimensions 50 cm X 30cm x 40 cm. It is made up of thin metal sheet. find the cost of metal sheet required to make 25 such boxes, if 1 m sq. of metal sheet costs Rs. 75. *

Answer 1

First we need to find the volume of the cuboid.

Since,

Volume of cuboid = L×B×H

= (50×30×40)cm

= 60000cm²

Since, the 60000 ÷ 100

= 600m²

Cost of 1 m² metal sheet = RS 75

So, cost of 600 m² metal sheet = 75×600

= RS45,000

Therefore cost of 1 box = RS 45,000

So, cost of 25 boxes = 45,000×25

= RS 1125000
