A: ### Quick Answer

**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.

## How many vertices does a circle have?

A:

Full Answer >**A circle does not have any vertices.**Vertices (plural for "vertex") are corners, or the place where two straight lines come together to form a point. Circles do not have straight lines that come together to form points.Filed Under: - Q:
## How Many Vertices Does a Cylinder Have?

A:

Full Answer >**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.Filed Under: - Q:
## How many vertices does a rectangle have?

A:

Full Answer >**A two-dimensional rectangle has four vertices, and a three-dimensional rectangle has eight.**The differences between the two figures are the number of sides and points of intersection.Filed Under: - Q:
## How many vertices does an octagon have?

A:

Full Answer >**An octagon has eight vertices.**An octagon is a shape with eight sides, which makes eight angles and, therefore, eight vertices.Filed Under:
