No, it is the other way around. The total number of edges is twice the number of edges on the base.
A pyramid has one more corner and faces than the number of sides in its base; thus a decagonal pyramid has 10 + 1 = 11 faces and corners. A pyramid has twice as many edges as sides in its base; thus a decagonal pyramid has 2 X 10 = 20 edges.
It is a true statement.
Yes, a cube has 6 faces and 12 edges
The only pyramid with a square base that has equilateral faces, is one where the diagonal of the base is exactly twice as long as the pyramid is high.

no each edge is counted by 3 so if u have like 6 edges you would count: 3,6,9,12,15,18
triangular pyramid
A pyramid has one more corner and faces than the number of sides in its base; thus a decagonal pyramid has 10 + 1 = 11 faces and corners. A pyramid has twice as many edges as sides in its base; thus a decagonal pyramid has 2 X 10 = 20 edges.
A triangular based pyramid would have 4 corners; three for the triangular base and one for the peak. A pyramid has twice as many edges as sides in its base; thus a triangular pyramid has 2 × 3 = 6 edges. A triangular based pyramid is called a tetrahedron.
A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices and 2n edges, where n >= 3.
It is a true statement.
A cube or a cuboid has 12 edges, 6 faces and 8 vertices
Yes, a cube has 6 faces and 12 edges
The only pyramid with a square base that has equilateral faces, is one where the diagonal of the base is exactly twice as long as the pyramid is high.
Okay. A square pyramid has 5 faces. So a pyramid with twice that would have 10 faces. You subtract 1 for the base and you get nine. Therefore you have 9 sides. Divide 72 by 9 and you get 8. So one side is 8 ft.
twice a number means a number times 2
