Answer:

192.5, third option

Step-by-step explanation:

The fastest way to do this is to find the volume of a rectangular prism with these measures and to divide it by 2. This is because a triangle is half of a rectangle, and likewise a rectangular prism is half of a rectangular prism.

So, the volume of a rectangular prism with the sides of 7 by 5 by 11 would be:

7 * 5 * 11 = 385

Divide this by 2.

385/2 = 192.5

Thus, the answer is 192.5.

(You could also find the area of the triangular base, then multiply that by the height.

Area of triangle: 7 * 5 * 0.5 = 17.5

Total volume: 17.5 * 11 = 192.5)
