no

They can have faces which are triangles, quadrilaterals, pentagons, hexagons or heptagons. It has 8 faces and can have 6 to 12 vertices.

No because they have 7 vertices

A heptagon has seven sides and a pentagon has five. So 2 heptagons and 2 pentagons have 2*7 + 2*5 = 14 + 10 = 24 sides altogether.

A heptagon has 7 sides and so 2*7 = 14 sides

2*8 = 16 vertices.

A heptagon has seven sides, a nonagon has nine, and a quadrilateral has four. So in 2 heptagons, 3 nonagons, and 3 quadrilaterals there are: (2*7)+(3*9)+(3*4) = 14 + 27 + 12 = 53 sides altogether.

A rhombus has 4 vertices, therefore a rhombic prism has 4 x 2 = 8 vertices.

A heptagon has seven sides, a quadrilateral has four, and a triangle has three. So 4 heptagons, 2 quadrilaterals, and 3 triangles have 4*7 + 2*4 + 3*3 sides = 28 + 8 + 9 sides = 45 sides.
