Answer:

S.A. = 60 in²

Explanation:

We have 4 congruent triangles.

The formula of an area of a triangle:


A_\triangle=(1)/(2)bh

b - base

h - height

We have b = 5in and h = 6in. Substitute:


A_\triangle=(1)/(2)(5)(6)=(5)(3)=15\ in^2

The Surface Area of the triangular pyramid:


S.A.=4\cdot15\ in^2=60\ in^2
