Question
A pyramid has a square base. Each side of the base is 12 cm. The slant height of each triangle is 14 cm. Find the surface area.
- 535 cm2
- 535.2 cm2
- 560 cm2
- 535.9 cm2
Hint:
The surface area of Pyramid = 
where p is the perimeter of the base , B is area of the base and l is the slant height of the pyramid.
The correct answer is: 535.2 cm2
Given, Each side of the square base is 12 cm. The slant height of each triangle is 14 cm.
Therefore, the surface area of the pyramid is 535.2 square centimeters.
