Question

The edge of a cube is increased by 100% the surface area of the cube is increased by?​

Answer 1

$400\%$

because

Answer 2

Answer:

4 times

Step-by-step explanation:

let the edge of cube= a

surface area of one face = a×a= a^2

total surface area of cube= 6×a^2=6a^2

now edge increased by 100%

new edge of cube= 2a

surface area of one face= 2a×2a=4a^2

totat surface area of new cube= 6×4a^2=24a^2

24a^2÷6a^2= 4

answer is 4 times
