Question

A(-1; 0; 1); B(-1;1;0); C(1;0;0) and D(0;1;1) are the vertices of the pyramid. Find the volume of this pyramid.

Answer 1

Since there are only 4 points, the pyramid is a triangular pyramid with volume of (1/2) x l x w x h
The length is 1, the width is 1, and the height is 1.
The volume is
(1/2) x 1 x 1 x 1
0.5 cubic units
