How many edges does a cuboid have?
A) 3
B) 4
C) 5
D) 6
E) 12
Answer:
E) 12
Explanation:
By elders formula, the numbers of faces F, of vertices V, and of edges E of any convex polyhedron are related by the formula F + V = E + 2. In the case of a cuboid, this gives 6 + 8 = 12 + 2; that is, like a cube, a cuboid has 6 faces, 8 vertices, and 12 edges.
