Example Question #1 : How To Find The Volume Of A Tetrahedron
In three-dimensional space, the four vertices of a tetrahedron - a solid with four faces - have Cartesian coordinates .
Give its volume.
A tetrahedron is a triangular pyramid and can be looked at as such.
Three of the vertices - - are on the -plane, and can be seen as the vertices of the triangular base. This triangle, as seen below, is isosceles:
Its base is 10 and its height is 18, so its area is
The fourth vertex is off the -plane; its perpendicular distance to the aforementioned face is its -coordinate, 8, so this is the height of the pyramid. The volume of the pyramid is
Example Question #651 : Geometry
In three-dimensional space, the four vertices of a tetrahedron - a solid with four faces - have Cartesian coordinates .
What is the volume of this tetrahedron?
The correct answer is not among the other responses.
The tetrahedron looks like this:
is the origin and are the other three points, which are fifteen units away from the origin on each of the three (perpendicular) axes.
This is a triangular pyramid, and we can consider the base; its area is half the product of its legs, or
.
The volume of the tetrahedron is one third the product of its base and its height, the latter of which is 15. Therefore,
