What is the Surface Area of a Square Pyramid?
Surface area of square pyramid = The sum total of each net surface that makes up the square pyramid.
a. An image of the net of the square pyramid is given in the diagram attached below.
The net is made up of 1 square and 4 triangles.
b. Surface are of the square pyramid = 4(area of triangle) + area of square.
= 4(1/2bh) + s²
b = 8 mm
h = 10 mm
s = 8 mm
Thus:
Surface are of the square pyramid = 4(1/2 × 8 × 10) + 8²
Surface are of the square pyramid = 224 mm²
