The three axes $O X, O Y$ and $O Z$ determine ............ .
Explanation
The three axes $O X, O Y$ and $O Z$ determine three coordinates planes.
36
The three planes determine a rectangular parallelopiped which has ............ of rectangular faces.
Explanation
Three points
37
The coordinates of a point are the perpendicular distance from the ............ on the respectives axes.
Explanation
Given points
38
The three coordinate planes divide the space into ............ parts.
Explanation
Eight parts
39
If a point $P$ lies in $Y Z$-plane, then the coordinates of a point on $Y Z$-plane is of the form ........... .
Explanation
We know that, on $YZ$-plane, $x=0$. So, the coordinates of the required point is $(0, y, z)$.
