SUMMARY

The equation "0 <= x <= 3, 0 <= y <= 4, 0 <= z <= 5" represents the boundaries of a cuboid in three-dimensional space. Each inequality defines a range for the respective coordinate: x is bounded by the planes x=0 and x=3, y is bounded by y=0 and y=4, and z is bounded by z=0 and z=5. These six planes collectively form the sides of a rectangular solid, confirming that the notation describes a cuboid rather than a singular equation.

PREREQUISITES

0 <= x <= 3, 0<= y <= 4, 0 <= z <= 5


The Attempt at a Solution


The notation is confusing me. Is the equation simply representing a cuboid?

If that's all the info you are given, yes.
 
That's not "an equation", it's three different inequalities. The first, 0\le x\le 3 means all points (x, y, z) such that the component, x, is between 0 and 3. That region is bounded by the two planes x= 0 and x= 3.
Similarly 0\le y\le 4 defines a region bounded by the planes y= 0 and y= 4. Finally, 0\le z\le 5 defines the region bounded by the planes z= 0 and z= 5. Those 6 planes form the 6 sides of a rectangular solid or cuboid.
