If all the dimensions of a cube are increased by 5 units, how will the surface area change?

Question

increase by a factor of 5
increase by a factor of 10
increase by a factor of 25
increase by a factor of 50

Answer 1

area of one side of cube =

(x+5)^2 = x^2 + 10 x + 25 = not something times original

I think you mean increase lengths by a FACTOR of five.
5^2 = 25

Answer 2

45.00

Answer 3

45.00
