Question

A paper weight is made in the shape of a triangular pyramid. The dimensions of the paper weight are shown.The formula for the volume of a triangular pyramid is V = one-third B h. Which expression can be used to find the value of B, the area of the base of the pyramid? B = one-half (9) (6) B = (9) (6) B = one-third (9) (7) B = (9) (7)

Explanation:

Answer 2

B = one-half (9) (6)

Explanation:

Volume of a triangular based pyramid = 1/3 × Base Area × Height

Since the base of the pyramid is triangular in nature, the area of the base will be equivalent to the area of the triangle.

Base area = Area of triangle = 1/2 × base × height

Given the height of the triangle = 6

Base of the triangle = 9

Base area = 1/2(9)(6)
