Question 1018735: As part of a sculpture,a girl wants to make a tetrahedron by welding together lenghts of steel.she has a 20m length of steel to use and she wants the sides of the tetrahedron to be whole numbers of metres.what is the lenghs of the side of the largest tetrahedron she can build? Answer by KMST(5328) (Show Source):
You can put this solution on YOUR website! She needs lengths to make the side of the base,
and more lengths to make the edges going from the vertices of the base to the apex of the pyramid/tetrahedron.
That is .
Dividing By , the whole number quotient is , with a remainder of .
The largest tetrahedron she can build has sides,
and she will have a length of steel leftover.
