Answer:
Step-by-step explanation:
we know that
The surface area of the regular pyramid is equal to the area of the triangular base plus the area of its three triangular lateral faces
step 1
Find the area of the triangular base
we know that
The triangular base is an equilateral triangle
so
The area applying the law of sines is equal to
step 2
Find the area of its three triangular lateral faces
we have
Find the height of triangles
Applying the Pythagorean Theorem
solve for h
substitute
step 3
Find the surface area
Adds the areas
Round to the nearest tenth
