Acube has a surface area of 181.5 sq in what is the length of its sides

The length of its sides are 5.5 inches.

Step-by-step explanation:

The formula of surface area of a cube

A = 6a²

Let the edge be x

181.5 = 6x²

x² =

x² = 30.25

x =

x = 5.5 inches.

The length of its sides are 5.5 inches.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
