Characteristics of a solid
A three dimensional (3D)
object that has one or
more curved or plane
faces. Has a length,
width and height.
Polyhedron
Round surface
A solid bounded by
polygons (ex:cube)
Having at least one curved surface (sphere,
cone, cylinder)
Prism
a solid having equal and
parallel sides. The base serves
to identify its name.
Pyramid
Square based pyramid
Triangular based pyramid
a solid made up of a base and
triangular shaped faces that converge to a
vertex.
Nets
Net : A way of presenting, in 2D, all faces of
a polyhedron.
Euler’s formula : V + F = E + 2
Face : each of the surfaces of a
polyhedron
Edge : Line formed by the meeting
of two surfaces
Vertex : A point common to at
least three or more edges (a
corner)
