Question

Each edge of cube in increase by 50% .Find the percentage increase surface area of cube?

Answer 1

Answer:125%

Explanation:

let the edge be 10

surface area= 6 *s²

                       =6*10*10

                         =600

edge increase by 50%

50% of 10=5

edge= 10+5=15

new surface area=6*15*15

                             = 1350

increased by = 1350-600=750

increase %= 750/600* 100
