Arectangular prism has a length of 8 in., a width of 4 in., and a height of 214 in.

the prism is filled with cubes that have edge lengths of 14 in.

how many cubes are needed to fill the rectangular prism?

enter your answer in the box.
to fill the rectangular prism,
cubes are needed.

For this case we have that by definition, the volume of a rectangular prism is given by:

Where:

It is the area of the base

h: It is the height

So:

The volume of the prism is:

Now, the volume of the cubes is:

Thus, we divide and find the number of cubes to fill the prism:

n = 2.5

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
