Question

he net of a square pyramid is shown: A square is shown having each side equal to 0.25 inch. Each side of the square has a triangle on it. The height of the triangle is labeled as 1.2 inches. What is the surface area of the figure?

Answer 1

0.6625

Explanation:

To find the surface area, calculate the area of each shape and add it together, A pyramid has 1 square and 4 triangles in its net,

Area of square is A=s*s=0.25*0.25=0.0625.

Area of a triangle is A= 1/2 b*h = 1/2 (0.25)(1.2) = 0.15.

There are four equal triangles so together there area is 4*0.15 = 0.60.

Add the square to it and you have the surface area of the pyramid.

0.0625 + 0.60 = 0.6625
