Question

I’m really bad at geometry pls help! Thanks

The right hexagonal pyramid
has a hexagon base with equal-length sides. The lateral
faces of the pyramid are all triangles (that are exact copies of one another) with
heights of 18 ft. Find the surface area of the pyramid.

Answer 1

Lateral area of the pyramid = 72 unit²

Explanation:

Lateral surface means side part of pyramid. So we nee need to find area of 6 triangles with base 4 and height 6.

Lateral area of the pyramid = 6 x Area of 6 triangles with base 4 and height 6

Hope this helped...
