Rectangular Parallelepiped

Rectangular Parallelepiped

    A three-dimensional figure all of whose face angles are right angles,
    so all its faces are rectangles and all its dihedral angles are right angles.
    (A dihedral angle is an angle created by two intersecting planes.)

Edges: a, b, c
Diagonal: d
Total surface area (total area of all
the faces of the figure): T
Volume: V

d = sqrt(a²+b²+c²)
T = 2(ab+ac+bc)
V = abc
Face diagonals: sqrt(a²+b²),sqrt(a²+c²),sqrt(b²+c²)

Cube

A three-dimensional figure with
six congruent square sides.
a = b = c

d = a sqrt(3)
T = 6a²
V = a³
Face diagonal a sqrt(2)
