Which expressions show the volume and the surface area of this cubed-shaped packing box?

,

Step-by-step explanation:

we know that

The volume of a cube is equal to

The surface area of a cube is equal to

where b is the length side of the cube

In this problem we have

Convert to an improper fraction

Part 1) Find the volume

substitute the value of b in the formula

Part 2) Find the Surface area

substitute the value of b in the formula

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

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
