Michael needs to wrap a gift that is shaped like a triangular pyramid. Each face has an area of 25 in². What is the surface area? (Hint: Figure out how many faces a triangular pyramid has)

If the answer is 75 ft², color is black if the answer is 100 in², color is red

A triangular pyramid is a pyramid having a triangular base. It has 4 faces, 6 edges and 4 vertices.

Since the area of one face is 25
in^(2)

Therefore, surface area of triangular pyramid = 4
* area of one face

=
25 * 4

= 100
in^(2).

So, the surface area of triangular pyramid is 100
in^(2).

Therefore, color is red.
