Question

Please help ASAP What is the surface area of the square pyramid represented by the net?

Answer 1

144

Explanation:

all of the triangles add up to 108m^2 and the middle adds up to 36m^2 so add them together and you get the surface area.

Answer 2

144 m²

Explanation:

From the diagram, we can see that the shape is made up of a square and 4 triangles. (We know it's a square as its width and length are equal).

First, find the area of the square.

Area of a square = width x length = 6 x 6 = 36 m²

All the triangles are the same, so we need to find the area of one of the triangles and multiply it by 4.

Area of a triangle = 1/2 x base x height = 1/2 x 6 x 9 = 27 m²

So the total area of all 4 triangles = 4 x 27 = 108 m²

Therefore the total surface area = 36 + 108 = 144 m²
