Is this what you mean?
Hopefully it is
The formula to find the volume of a prism is V=Bh (Volume = Base x height). Let's plug in the dimensions you were given:
V=Bh
V=(5)(10)
V=50 {tex] ft^{2} [/tex]
To find the new volume of the dilated prism, cube the dilated factor, then multiply by the volume you just found (old volume):
New Volume = (

)(Old Volume)
V = (

)³·50
V = (

V = 86.4
Since all the answer have the letter r in it, r would be the unknown number.
In math the "/" line represents division.
So 50 divided by an unknown number would become 50/r/
The answer is D.
I found that the answer is 10
