Question

What is the formula for a triangular pyramid?
A. (0.5*Length*Width)* Height
B. (0.5/Length*Width)* Height
C. 1/5 (0.5* Length * Width)* Height
D. 1/3 (0.5*Length*Width) *Height
Please help me :(

Answer 1

The answer would be D. because:
1. A is saying the formula to a triangular prism.
2. B is saying the formula to a triangular prism but instead of multiplying, it's dividing 0.5 by length.
3. C is saying the formula to a triangular pyramid BUT it has 1/5 and the formula should have 1/3.

Answer 2

The formula for calculating the surface area of a triangular pyramid involves the area of the base, the perimeter of the base, and the slant height of any side of the pyramid. The surface area of a triangular pyramid is Base Area +1 2 (Perimeter×Slant Height) Base Area + 1 2 (Perimeter × Slant Height).
