Question

If all the dimensions of a cuboid are increased by 100%, by what per cent
does the volume of cuboid increase?​

Answer 1

Answer:

First of all consider the following things

Let the length of cuboid be = L units

Let the breadth of cuboid be=B units

Let the height of cuboid be = H units.

Now, given that each edge is increased by 100 %

So following changes takes place.

Length = 2 L units

Breadth = 2 B units

Height =  2 H units

Volume of cuboid = L*B*H

So the new volume = 2 L *  2 B *  2 H

= 8 (L*B*H)

= 8 (L*B*H)×100/ L B H

So the volume got increased by  800 %
