azamat

Answer:

62.4 square centimeters

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The surface area of the triangular pyramid is equal to the area of the triangular base plus the area of its three lateral triangular faces

In this problem the triangles are equilateral, that means, the

surface area is equal to the area of four congruent equilateral triangles

$A=4[\frac{1}{2}(b)(h)]$

we have

$b=6\ cm\\h=5.2\ cm$

substitute

$A=4[\frac{1}{2}(6)(5.2)]=62.4\ cm^2$
