# Math Help - In the first octant?

1. ## In the first octant?

hello
If I have problem about finding the volume of the solid lies in the first octant

What I will get from "in the first octant" ?
What is the given informations in it ?

2. Think of the first quadrant of a standard xy-plane. This is where x and y are positive.

The first octant is the same concept, but instead we are dealing with the xyz-plane (3 dimensions) and x, y, and z are all positive.

3. $x,y,z\ge0.$
