Solid Figures
Introduction
Solid figures have special names.
Cube
Cylinder
Rectangular
prism
A sphere is a ball
shape. It has no faces.
A cylinder is a can
shape. It has 2 faces
that are circles. These
faces are called bases.
Pyramid
Sphere
A cone has a curved
surface and 1 base
that is a circle.
Cone
Some solids have curved surfaces. Some have flat faces that are plane
figures.
A prism is a solid that has rectangles for the sides and two polygons for
bases. The base can be any polygon.
This solid is a rectangular prism.
It has 6 faces, 12 edges, and 8 vertices.
It has 4 faces that are rectangles. They
are the sides. It has 2 faces that are
squares. They are the bases.
Vertex
Face
Edge
A pyramid is a solid that has triangles for the sides
and one polygon for a base. The base can be any
polygon. The sides meet at one point.
This solid is a rectangular pyramid.
It has 5 faces, 8 edges, and 5 vertices.
It has 4 faces that are triangles. They
are the sides. It has 1 face that is a
square. It is the base.
A cube is a special
kind of rectangular
prism. All the faces
are squares.
Faces are the sides
and bases of solid
figures.
Vertex
Face
Edge
The edges are where
the faces meet.
The vertices are the
corners where the
edges meet.
