12 Math Vocabulary-Volume

Three-dimensional shape, or solid, takes up space.  Examples of solids are:  cube, prism, cylinder, cone, and pyramid.^[1]

Cube:  It has flat, polygon-shaped surfaces called faces.

                                ^[2][3]

Face  All t^[4]he faces of a cube are squares.  Faces meet along segm^[5]ents called edges and edges meet at points called vertices.  The singular of vertices is vertex.

Edge:  Segments where faces meet on a cube, or other solid shape.

Vertex (plural) vertices:  The points where edges meet on a cube or other solid shape.

Prism:  A solid with two parallel bases that are the same size and shape and faces that are parallelograms.

Cylinder:  A solid with two circular bases that are parallel and the same size and shape.

Cone:   A solid with one circular base.  The points on this circle are joined to one point outside the base.

Pyramid:  A solid with one base that is a polygon and whose other faces are triangles with a common vertex.

Volume:  The number of cubic units needed to fill a solid figure.  

Cubic Unit:  The volume of a cube one unit on each edge.
