Question

an open box has ____ faces
a) 5
b) 6
c) 7​

Answer 1

Answer:

By Euler's 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.

Step-by-step explanation:

hence an open box have 6 faces

Answer 2

Answer:

a normal closed box has 6 faces but if one side is open then it will have 5 faces thus an open box has 5 faces
