Pyramid with a hexagonal base
Octohedron
To fined the area of a triangle use the formula 1/2 one have times base times height if the base of the triangle is 6 miters and the height is 8 miters your formula would look like this. 1/26*8 6*8 = 48 1/2 divided by 48 or 48/2= 24 the Answer is D. 24 meters
A hexagonal pyramid
a triangle has 1 face but if you mean a pyramid (3-D triangle) it has4 but a (a 3-D triangle with a square bottom) it has 5.
It's the bottom of a 3-D shape or solid. For example, a square-based prism. The square face would be the base. Here's another example, a triangluar-based pyramid. The triangle would be the base.

There is only one, if you are speaking of a regular triangle drawn on a paper. However, if you are speaking about a pyramid, similair to the triangle but in 3-D, then there are 5. All of the sides are made of triangles apart from the base, which is a square.
There are infinitely many such shapes.
