What is the surface area of the pyramid

14 multiplied by 8. then divide by two. that's the area of one triangle. multiply answer by 3 to find area of all the triangles.

14 * 8 = 112 / 2 = 61 * 3 = 183

8 multiplied by 6.9. then divide by 2. that's the area of the base. add both answers.


8 * 6.9 = 55.2 / 2 = 27.6


183 + 27.6 = 210.6


210 in. squared is the answer.


hope that you.
