Well, the surface area of a tetrahedron is 4*(area of each side).

Since a tetrahedron is made of 4 triangles, 4*(1/2*base*height)

The volume is simply (1/3)*(area of base)*(height)

As far as making a tetrahedron

Not sure what you mean about "5 tetrahedron"

*takes out anthor chewy bar and eats that one*

What I mean bye 5 tetrahedron is show as my image 5 interlocking triangles

*picks up trash from chewy bars and takes out anthor one*

Are you sure? There are no 5 sided isohedra. (tetra means 4, it's from greek)

Really? Well try explaing that to my teacher let me give you a link I found for it

Here one url I found let me find the other
Origami Geometric Constructions (http://kahuna.merrimack.edu/~thull/fit.html)

Here the other url
Instructions for making the compound of 5 tetrahedrons (http://www.cs.utk.edu/~plank/plank/pics/origami/5tet/)

That's a "compound of 5 tetrahedrons" not a "5 tetrahedron"! Anyway now we are on the same page!

Okay so can u help meh?

And I'm sorry about confusing both of us
