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 quick plz!!

Answer 1

SA = 124 cm²

Explanation:

The lateral surface area is the area of all sides besides that base, so 93 cm² is the sum of 3 sides of the tetrahedron.

93/3 = 31 cm² per side, there are 4 sides, so 31(4) = 123 cm² is the total surface area
