A favorite item at the fair is bacon on a stick. If each stick holds approximately 0.15kg of bacon and the booth serves an average of 45 people an hour, how many pounds of bacon are consumed in the 12 days of the fair? (The gates open at 6:00am and close at midnight.)

Use the conversion factors you already know, but when you square or cube the unit, don’t forget to cube the number also!

Best way: Square or cube the ENITRE conversion factor

Example: Convert 4.3 cm3 to mm3

4.3 cm4.3 cm33 (10 mm) (10 mm) 33

(1 cm)(1 cm) 3 3 = 4.3 cm4.3 cm33 10 1033 mm mm33

1 133 cm cm33

= 4300 mm3

1000 cm3 (1 dm)3

(10 cm)3 = 1 dm3

So, a dmSo, a dm33 is the same as a Liter ! is the same as a Liter !

A cmA cm33 is the same as a milliliter. is the same as a milliliter.

How many liters of water would fill a container that measures 75.0 in3?
