The easiest way to do this, is to go ahead and convert our fractions to decimals, meaning we divide 2 by 12, and 2 by 14. This helps us have all our measurements in the same form so we can just plug them into our formula. [tex] \frac{2}{12} =.16[/tex] [tex] \frac{2}{14} =.14[/tex] The formula for a rectangular prism is really easy: V=L*W*H Volume=Length times Width times Height. .16*4*.14= 0.09 (Roughly) Please keep in mind I only used the tenths, and hundredths place; the actual answers are much longer.
