Question
Tetraethyl lead is a compound previously added to gasoline to improve the anti knocking properties and performance. Some leaded gasoline contains about a gram of lead in each gallon. At LCC 5,500 cars commute an average of 15 miles each in cars that get an average gas milage of 19 miles per gallon. How many grams of lead are released each time these cars drive? The answer was 4.342 kg and then 9.5724 lbs (when you multiply by 2.2046 lb/kg)
The question then asks. If it was all in a cube, what would the length of the side be? Use one-line dimesnsional analysis for each problem. The answer is supposed to go from lbs to inches.
Explanation / Answer
lead is 0.40968 lbs/in^3, so, 9.5724/0.40968 = 23.3656 in^3 of lead, and take the cube root of that to find the length of a side, (23.3655)^(1/3) = 2.86 inches
