A triangular pyramid has lateral faces with bases of 6 meters and heights of 10 meters. The area of the base of the pyramid is 15.6 square meters. What is the surface area of the pyramid?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
