Sides = 9 Faces = 5
There are 3
Same thing
a rectangular prism has Six sides
Two more.
A decagonal prism has 12 faces.
Sides = Faces: 9 Edges: 21.
There are 9 edges
Five
It will have 8 faces.
6 faces
This question is not the clearest. However, an n-sided prism will typically have n+2 faces: the n sides, and the two ends. So a nine-sided prism will have 11 faces.
A prism has two polygonal faces at each end and these may have any number of sides, n. The prism also has n rectangular faces.
