Question

If each edge of a cube is increased by 50%, then the percentage increase in its surface area is

Answer 1

Step-by-step explanation:

Let the original side be a then

Original surface area S=6a2

When side is increased by 50%, side becomes 23a then

Surface area s=227a2

Hence,

Surface area is increases by x=6a2227a2−6a2×100=125%

This is the required solution
