Question

If each side of cuboid is increased by 10%. What is the % increase in the serface area of the cubiod.

Answer 1

Answer:

This is a really easy question.

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 20 %

So following changes takes place.

Length = 1.2 L units

Breadth = 1.2B units

Height = 1.2 H units

Volume of cuboid = L*B*H

So the new volume = 1.2 L * 1.2B * 1.2H

= 1.728(L*B*H)

=1.728 of original cuboid

So the volume got increased by 72.8%
