Option A. 10 faces
Explanation:
Euler's formula says, if a solid has F number of faces, V number of vertices, and the number of edges then
F + V - E = 2
Now we have to calculate the faces of a solid which has 8 vertices and 16 edges then
F + 8 - 16 = 2
F - 8 = 2
F = 8+2
F = 10
Therefore, option A. 10 faces will be the answer.
