Question

Help for brainiest

Answer 1

Answer:

Option D

Step-by-step explanation:

Formula to use: V=$\frac{1}{2}(b*a)*h$

b=base of triangle   a=altitude of triangle  h=height of prism

Doing $\frac{1}{2}(b*a)$ is essentially finding the area of the triangle and after multiplying by h will give you the volume of the triangular prism.

Solve: V = $\frac{1}{2}(3*3)*7$  or option D

Ps. Altitude is perpendicular or 90 degrees to the side I used for the base, so it wouldn't be option C.
