  2. 2. www.numeracysoftware.com Cuboid Key Feature Six faces which are all rectangles. Faces 6 Corners 8 Edges 12Planes of Symmetry?If the cuboid has no square faces then it has ... three.If two opposite faces are square then it has ... five.Is a Cuboid a Prism?Yes, because it has a rectangular cross-section throughoutits length.
  3. 3. www.numeracysoftware.com Cube Key Feature Six faces which are all squares. Faces 6 Corners 8 Edges 12Planes of Symmetry?NineIs a Cube a Prism?Yes, because it has a square cross-section throughout itslength.
  4. 4. www.numeracysoftware.com Prism Key Feature The shape of its cross-section is the same throughout its length. Faces, Corners, Edges? It depends what sort of prism it is. Planes of Symmetry? It depends what sort of prism it is.Examples of prisms include triangular prism, hexagonal prism,cuboid, cube and cylinder.
