b) If we add a triangular pyramid on top of a triangular prism and a rectangular
pyramid on top of a cuboid, which shape will have more edges, faces, and
vertices? How many lines of symmetry can you pass through each figure?​

Answer 1

Triangular prism

Faces - 5

Vertices - 6

Edges - 9

(F+V) - E By Using This Formula (Euler's Formula )
