Question

This is a picture of a square pyramid and the net for the square pyramid.

What is the surface area of the square pyramid?
A.) 108 ft^2
B.) 152 ft^2
C.) 192 ft^2
D.) 240 ft^2

Answer 1

The surface area of the square pyramid can be calculated by adding the area of the base to the sum of the areas of the four triangular faces.

The area of the base is 10² = 100 ft².

The area of each triangular face can be calculated as 1/2 × base length × height, where the base length is 10 (same as the square side length) and the height is given as 12.

Therefore, the area of each triangular face is 1/2 × 10 × 12 = 60 ft².

The total surface area is the sum of the base area and the four triangular face areas, which is 100 + 4 × 60 = 340 ft².

So, the surface area of the square pyramid is 340 ft².

Hope this helps!

Answer 2

Mine has 12 instead of 11 and 10 instead of 8
