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
