Each edge of a cube is increased by 50%. What is the percent increase in the surface area of the cube? (Surface area= 6e2)

Question

word problem

Answer 1

For this question you can plug in a number for "e" and then see what happens when you increase it by 50%.

 

Let's say the length of an edge is 2

 

Surface area = 6(2²) = ?

 

A 50% increase would make the new edge length 3

 

Surface area = 6(3²) = ?

 

Then check to see what the % increase from the first number to the second number.
