Question

The surface area of a triangular pyramid is calculated using the formula:

A) (1/2) * base * height
B) base * height
C) (1/3) * base * height
D) base + height

Answer 1

The formula for the surface area of a triangular pyramid is (1/2) * base * height. Given specific values for the base and height, we can calculate the area. The correct option is A.

Step-by-step explanation:

The formula for calculating the surface area of a triangular pyramid is (1/2) * base * height.

Let's calculate the area of a triangle using this formula. Given that the base is 1.007 m and the height is 0.665 m:

Area = (1/2) * 1.007 m * 0.665 m

Area = 0.334 m² (rounded to the proper number of significant figures).

Hence, A is the correct option.
