A triangular pyramid has lateral faces with bases of 6 meters and height of 9 meters. The area of the base of the pyramid 15.6 meters. What is the surface area of the pyramid?

To find surface area, you can find the area od all sides and add them together

First, area of an triangle is 1/2 length times width

So you do 1/2 6*9 = 1/2 54 = 27 The area of the three triangles are 27

27 times 3 is 81

81 plus the base of 15.6 is 96.6

The surface area is 96.6 meters squared
