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.
Know MoreA 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.
Learn more about ShapesA pentagonal prism has 10 vertices because there are two five-sided shapes at both ends of a prism. A pentagonal prism has 15 edges and seven faces. Five faces are between the pentagons on each end.
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.
Full Answer >A triangle has three vertices. A triangle consists of three lines, and the location where one line endpoint meets another line endpoint is called a vertex. A square consists of four vertices, while an octagon contains eight vertices.
Full Answer >An octagon has eight vertices. An octagon is a shape with eight sides, which makes eight angles and, therefore, eight vertices.
