A cuboid has 12 edges. A cuboid is a box-like shaped polyhedron that has six rectangular plane faces. A cuboid also has six faces and eight vertices.
Know MoreKnowing these latter two facts about a cuboid, the number of edges can be calculated with Euler’s polyhedral formula. This formula states that the number of faces (F) plus the number of vertices (V) minus the number of edges (E) equals 2, or F + V - E = 2.
By substituting 6 for V and 8 for V in this equation, it becomes 6 + 8 - E = 2, or 14 - E = 2. From this equation, it is simple to see that E equals 12.
Learn MoreA cuboid is a shape that looks similar to a box and has six flat sides. Cuboids also have only right angles, and all of the faces are rectangles.
Full Answer >In strict geometric terms, a cone does not have any edges. Since a cone lacks a plane and an edge in geometry is the location where two planes intersect, it does not have any edges.
Full Answer >A cube is a six-faced, three-dimensional figure composed of square-shaped faces of the same size that meet at 90-degree angles, whereas a cuboid is a box-shaped object made of six faces that all meet at 90-degree angles. A cuboid shape can also be a cube if all sides are the same length, but not all cuboids are cubes. Cubes and cuboids contain eight vertices and 12 edges.
Full Answer >A three-dimensional rectangle is called a cuboid. A cuboid is defined as a closed box that is composed of six rectangular faces joined at right angles. The rectangles on opposite faces of the cuboid are identical to each other.
