Parts of a rectangular parallelepiped

FaceAlso called facets or sides. A rectangular parallelepiped has six faces which are all rectangles, so all four interior angles are right angles.

EdgeA line segment formed where two edges meet. A rectangular parallelepiped has 12 edges. VertexA point formed where three edges meet. A rectangular parallelepiped has 8 vertices.

QUESTIONS:

1. Give the lateral area, surface area and volume of a rectangular parallelepiped if it measures 20x50x30:

2. Give the lateral area, surface area and volume of the rectangular flower box which have 20 cm in height, 14 cm wide and 50 cm long.

In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube can also be called a regular hexahedron and is one of the five Platonic solids. It is a special kind of square prism, of rectangular parallelepiped and of trigonal trapezohedron. The cube is dual to the octahedron. It has cubical symmetry (also called octahedral symmetry). It is special by being a cuboid and a rhombohedron. -------------------------------------------------

CUBE

Parts of a cube

FaceAlso called facets or sides. A cube has six faces which are all squares, so each face has four equal sides and all four interior angles are right angles.

EdgeA line segment formed where two edges meet. A cube has 12 edges. Because all faces are squares and congruent to each other, all 12 edges are the same length.

VertexA point formed where three edges meet. A cube has 8 vertices.

QUESTIONS:

1. Give the volume, surface area and lateral area of a box if it has a measurement of 6 x6 cm.

2. Give the volume,surface area and lateral area of a rubik’s cube if its side measures 8 cm.
