Volume of Rectangular Prisms

REVIEW - a three-dimensional figure encloses a part of space

Three-Dimensional Figures faces – the flat surfaces edges – the segments formed by intersecting faces vertices – the points formed by intersecting edges

faces edges vertices

A three-dimensional figure encloses a part of space. prism – has two parallel and congruent bases in the shape of polygons; the shape of the bases tells the name of the prism

A three-dimensional figure encloses a part of space. pyramid – has a polygon for a base and triangles for sides; the shape of the base tells the name of the pyramid

A three-dimensional figure encloses a part of space. cone – has curved surfaces, a circular base and one vertex

A three-dimensional figure encloses a part of space. cylinder – has curved surfaces, two circular bases and no vertices

A three-dimensional figure encloses a part of space. sphere – has no faces, bases, edges, or vertices; all the points are the same distance from a given point called the center

volume – the amount of space inside a three-dimensional figure The volume (V) of a rectangular prism equals the product of its length (l), its width (w), and its height (h). V = lwh h w l

volume – the amount of space inside a three-dimensional figure The volume (V) of a cube equals the product of three of its sides (s). V = s3 s s s
