## A Tetrahedron

You are given six sticks of integral lengths 1, 2, 3, 4, 5 and 6.
Using these sticks, can you make a tetrahedron (4-sided, 3-D
figure, with a triangle on each side)? If so, show how.
If not, replace any one of the
sticks with the smallest stick of integral length greater than
6 that allows you to build such a tetrahedron and show how it
can be done.
