Answer»

Prism is a polyhedron with two polygonal faces lying in parallel planes and with the other faces parallelograms

Euler’s formula, F + V = E + 2

Here number of faces, F = 5

Number of vertices, V = 6Number of edges, E = 9Consider, F+V = 5 + 6 = 11E + 2 = 9 + 2 = 11Hence F + V = E + 2Thus Euler’s formula is verified

A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. It is the idealized version of a solid physical tin can having lids on top and bottom.

No of faces =3No of edges=2

draw a net for a cube with an edge 3.5 cm
