Find the length of a rectangle of a parallelepiped, the volume of which is 13.5 cm3, width 4.5 cm and height 4 mm.

Given:

V = 13.5 cm³;

b = 4.5 cm;

c = 4 mm = 0.4 cm,

a =? cm.

Determine the length of the rectangular parallelepiped:

V = a b c,

a = V: b: c = 13.5: 4.5: 0.4 = 7.5 cm.

Answer: a = 7.5 centimeters.
