I'm pretty sure that it is 30
A die had 12 edges. The number of edges that dice have will depend on the number of dice!
12 edges
10 number of faces +2 gives you the number of edges
12
12 Edges (That's one number.)
There are twelve edges in a rectangular prism.
Edges: 4, Vertices: 4 and Edges: still 4, their number hasn't changed!
A pyramid with a polygonal base has as many edges as the number of sides of its base plus the number of edges in the base. A 100-gon pyramid would have 100 edges on its base and an additional number of edges equal to the number of sides of the base, which is also 100. Therefore, a 100-gon pyramid would have 100 + 100 = 200 edges.
The number of edges of the base of a prism can be used to calculate the total number of edges by first determining the number of edges on one base. For example, a rectangular prism has 4 edges on its base. Then, multiply this number by 2 to account for the top and bottom bases. Finally, add the number of edges around the sides of the prism, which is the same as the number of edges on the base. So, in total, the number of edges of a prism can be calculated as 2 times the number of edges on the base plus the number of edges around the sides.
If you are asking for the number of edges on a cube, I think its 12.
