ok this is not math but do be mean about it ok.

What are you talking about , siem?    A triangle can have side a and side b and side c = 1

abc all =1 can this happen how do i find the volume. 

1+1+1=3/2=1.5

is that right or wrong. 

If that is the side lengths of a rectangular prism ( a cube)      l x w x h = 1 x 1 x 1 = 1 cubic unit.

so it will be 1 ok thank you.
