Find the volume of the prism.

The answer is B.
**
The triangles on the two ends are congruent. So, to find the prism area, it is enough to take the area of one of the triangles and multiply it by the prism depth, which is 20 units.
Use the Pythagorean theorem to find the height of the triangle. 5^2 - 3^2 = 4^2, so the height is 4. Multiply half times height times base: 1/2 x 4 x 3 = 6. Multiply that by the depth, 20. 6x20=120. The answer is in cubic units, or units^3

The correct option is B.

Any prism volume is V = BH where B is an area of the base and H is the height of the prism, so find the area of the base by B = 1/2 h(b1+b2), then multiply by the height of the prism.

How to Find the volume of the prism?

The triangles on the two ends are congruent.

So, to find the prism area, it is enough to take the area of one of the triangles and multiply it by the prism depth, which is 20 units.

Use the Pythagorean theorem to find the height of the triangle.

5^2 - 3^2 = 4^2, so the height is 4.

Multiply half times height times base: 1/2 x 4 x 3 = 6.

Multiply that by the depth, 20.

6x20=120 units^3.
