Find the volume of a rectangular parallelepiped that is 21cm long and three-sevenths of its width and 30% of its height.

The volume of a rectangular parallelepiped is equal to the product of its measurements:
length x width x height.
Length = 21 cm.
Width = 3/7 (length) = (3/7) * 21 = 9 (cm).
Width = 30% of height = 0.3 * (height). From where we determine the height of the parallelepiped:
Height = (width) / 0.3 = 9cm / 0.3 = 30cm.
Volume = length x width x height = 21 cm * 9 cm * 30 cm = 5670 cc.
