The volume of a prism is given by:

We know that the height is x. The length is 25 shorter than x, this can be express as:

The width is 14 longer than x, this can be express as:

Plugging the expressions for the length, the width and the height we have that:

Therefore, the volume of the prism is:
Answer:
Option B. 
Step-by-step explanation:
we know that
The volume of a cone is equal to

Solve for the radius r
That means-----> isolate the variable r
Multiply by 3 both sides

Divide by
both sides

square root both sides

A] if .8=1 liter water, then .2=(1/4)(1)=.25 milk-->1.25liters in total
B] .25 liters
