you need to find a common denominator to all the fractions. for instance, 30 would be one. convert each number to have the common denominator and then just multiply the numerator.

Convert them all to fractions and then multiply them:
--whenever you multiply fractions you multiply the tops (numerators) and bottoms (denominators) separately, you only have to find a common denominator when adding or subtracting.
5 1/2 * 3 4/5 * 6 2/3
=11/2 * 19/5 * 20/3
=4180/30
=139.3333, or 139 1/3

5 1/2 = (5 x 2 + 1)/2 = 11/2
3 4/5 = (3 x 5 + 4)/5 = 19/5
6 2/3 = (6 x 3 + 2)/3 = 20/3
11/2 x 19/5 x 20/3 =
11/2 x 19/1 x 4/3 = 836/6 = 139 1/3

Just multiply the three numbers together. you'll most likely have to convert 5 1/2 to 5.5, etc.
The answer is 139 1/3 or 139.33333333(repeating) cubic units.
