Question

A tetrahedron is a triangular pyramid whose four faces are identical equilateral triangles. The total lateral surface area is 93 square centimeters. Find the surface area of the tetrahedron.

Answer 1

Answer:

Step-by-step explanation:

The total area is four times a face area and the lateral area is three times a face area.

Let x be the total surface area then

x/93=4/3

x=4(93)/3

x=372/3

x=124 cm^2
