Q:

# How many vertices does a cuboid have?

A:

A cuboid always has eight vertices. A cuboid is a three-dimensional shape that is similar to a cube in that it has six faces that are all at 90-degree angles to each other, but at least two of the faces on a cuboid are rectangles, not squares.

A cuboid can describe an infinite amount of six-sided, 3-D shapes that have rectangular sides. Up to four of the sides can be square, but if six sides are squares it is no longer a cuboid, but a cube. To calculate the volume of a cuboid, multiply the length, width and height together.

A cylinder has zero vertices. A cylinder does not have a vertex because there is no point where two lines meet. This is because a cylinder, unlike a prism, has circular faces; there is no corner where two straight lines meet.
