Question

Each edge of a cube is increased by 50%. What will be the percent increase in its volume?
A. 50 %
B. 150 %
C. 133 ¼ %
D. 237 ½ %

Answer 1

Answer: The surface area of the cube is increased by 125% Each edge is increased by 50%, if it was originally x, now it's 1.5x. The area of each face was originally x^2, now it's 2.25x^2. Therefore the area of each face is increased by125%, and so is the total surface area of the cube.

Answer 2

Step-by-step explanation:

Let edge = a

Volume = a^3

If edge increases by 50% then edge =1.5a

New Volume = (1.5a)^3

= 3.375a^3

Increase = 3.375a^3-a^3

= 2.375a^3

Increase %= 2.375a^3/a^3 *100

= 237.5%
