Question

If side of a cube is increased by 50% then what percentage increase will be in the area of the faces of the cube?

Answer 1

LET THE SIDE OF CUBE IS 10

AREA= 6SIDE SQUARE= 6*10*10=600

NOW THE SIDE IS INCREASED BY 50% MEANS NOW SIDE IS 15

NEW AREA=6*15*15=1350

INCREASE IN THE AREA=(1350-600)*100/600=750/6= 125%
