The Lateral surface of the triangular pyramid = 6 cm²
How to Find the Lateral Surface of a Triangular Pyramid?
The lateral surface of a triangular pyramid is the area of the three triangular surfaces of the triangular pyramid, which excludes the area of the base.
The area of each triangular face = area of triangle = 1/2(base)(height).
Given the following as shown in the diagram:
Height of the triangular face = 7.2 cm
Base length of the triangular face = 5 cm
Lateral surface of the triangular pyramid = 3(1/2 × base × height)
Plug in the values
Lateral surface of the triangular pyramid = 3(1/2 × 5 × 7.2)
Lateral surface of the triangular pyramid = 3(18)
Lateral surface of the triangular pyramid = 6 cm²
