Volume of triangular prism is 20 cm^3. The base triangle has an area of 5cm^2. What is the height of the prism?

Do it like a bad at math 7th grader did it and show your work.

Okay, so first I know that the volume of a prism is the area of the base triangle times the height. The area of the base triangle is 5 cm^2. And the volume is 20 cm^3. So, the height must be 20 / 5 = 4 cm. So, the height of the prism is 4 cm.
