Question

The following figure shows a square-based pyramid.

Which expression represents the surface area of the pyramid?

Answer 1

Answer:

A

Step-by-step explanation:

surface area is solving for the entire surface. Thus, you find the area of the triangles and the square base.

Answer 2

The expression that represents the surface area of the pyramid is 16 + 4+ 4+ 4+4

Total surface area of a pyramid

The total surface area of the shape is the sum of all the area of its faces.

The given pyramid has 4 triangular faces and a square base

TSA = area of the 4 triangles + base area

TSA = 4(0.5(4*3)) + (4 * 4)
TSA = 4(6) + 16
TSA = (6 + 6 +6 + 6) + 16

Hence the expression that represents the surface area of the pyramid is 16 + 4+ 4+ 4+4
