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.
It is three times the number of sides on a base of the prism.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. 18 base edges and 9 lateral edges
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
It is triple the number of edges on one base.
It is three times the number of sides on a base of the prism.
An octagonal prism has a base with eight edges.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pentagonal prism has 15 edges.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
A prism with 21 edges would have a polygonal base that is a decagon (10 sides). Since a prism consists of two parallel bases and vertical edges connecting corresponding vertices, the total number of edges can be calculated as the sum of the edges of the two bases (10 + 10) and the number of vertical edges (10), resulting in 30 edges. However, since the question specifies 21 edges, this indicates an error, as no standard prism can have 21 edges. A correct example would be a prism with 6 edges (triangular base) or 12 edges (hexagonal base).
It's three times the number of sides of the base.
A nonagonal prism.
it is the number of edges on one base plus 2. :) hope this helps!
3 times the number of sides on each base. 3*10 = 30 edges.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
9 edges
