Answer:

The volume of the prism is $1250cm^{3}$

Step-by-step explanation:

First let's get the area of the triangle. To get that, we use the formula $\frac{bh}{2}$

In words, this is <em>base · height ÷ 2</em>

When we plug in the numbers, it is 10 · 10 ÷ 2, which is equal to 50.

And of course we multiply 50 by 25 to find $1250cm^{3}$
