What is the volume of an tetrahedron with edge length of 1?

Question

Please show solution..

Answer 1

It is a pyramid; volume = 1/3 (area of base)(height)

Area of base = sqrt(3) / 4 as it's an equilateral triangle with sides 1
Height = the leg of a right triangle with hypotenuse 1 and other leg sqrt(3)/3
= sqrt(6)/3

Volume = 1/3(sqrt(3)/4)(sqrt(6)/3) = sqrt(24)/36 = sqrt(6)/18

Don't bet your house on this as it's late but I think it's right!

Answer 2

Yikes, thought i coudl figure this, but it's beyond me tonight. Good luck finding someone to help....
