A wooden block has rectangular faces and sides of lengths L, W, and H. The faces have areas of 18.7 cm2, 38.5 cm2, and 23.8 cm2 as shown. Find the lengths of the sides. 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

W * L = 38.5

W * H = 18.7

L * H = 23.8

------------------

W = 18.7 / H

L = 23.8 / H

------------------

W * L = 38.5

(18.7 / H)(23.8 / H) = 38.5

H = 3.4 cm

W = 18.7 / H = 5.5 cm

L = 38.5 / W = 7 cm
