Answer:

B, 82 meters cubed

Step-by-step explanation:

The formula for volume of a triangular pyramid is <u>1/3Ah, where A = the area of the triangular base, and h = the height of the pyramid</u>.

The area of the base here is <u>1/2 base x height, so</u>:

1/2 x 8.2 x 4 = 1/2 (32.8) = 16.4 meters squared.

Plug this into the formula for the volume of the pyramid:

1/3 x 16.4 meters squares x 15 meters = 82 meters cubed
