How many cubes with side lengths of 1 3 cm 3 1 cmstart fraction, 1, divided by, 3, end fraction, start text, space, c, m, end text does it take to fill the prism?

Step-by-step explanation:

Given that the length of the prism is cm, and  it is made up of eight cm cubes

The width is cm, so it is made up 3 rows of cm cubes

That means the bottom layer of cubes is made up of 3 rows of 8 cubes

∴ the bottom layer is made of 24 cubes

The height is cm, so it is made up of 2 layers of cm cubes.

So there are 2 layers of 24 cubes

∴ 48 cubes takes to fill the given prism.

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
