Question

Find the total area of the regular pyramid.
Height: 8
Side: 6

Look at picture attached below

Answer 1

Area is 6 times area of face and base triangles.

On base, radius = 3/cos 60 = 6, height = 3 sqrt 3, area is 9 sqrt 3.

On face, long side is 10, height is sqrt 91 and area is 3 sqrt 91.

Total area 6 * (9 sqrt 3 + 3 sqrt 91) = 54 sqrt 3 + 18 sqrt 91.
