The total surface area of a cube is 1350sqcm find volume?

Step-by-step explanation:

There are 6 square faces to a cube, so each square has area 1350/6 = 225sqcm

The area of a square = length^2 where length is any side's length (they are all the same)

√225 = 15cm length

This makes the cube have volume 15^3 = 3375 cubic cm

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
