Part I: Units of Measurement (60 Points)
(1) Given that 1 zig = 9.87 zags, and 1 ping = 6.54 pongs, convert a measurement of 1.23 zigs / ding to units of zags / pong. Express your answer to three significant figures.
(2) (a) One acre = 43,560 square feet. One yard = 3 feet. Determine how many square yards are in one acre.
(b) One hectare = 10,000 square meters. I kilometer = 1000 meters. Determine how many square kilometers are in one hectare.
(3) Consider a swimming pool measuring 25.0 meters long x 10.0 meters wide x 3.0 meters deep.
(a) Calculate the volume of the pool in cubic meters.
(b) Given that 1 meter = 100 centimeters, 1 cubic centimeter = 1 milliter, 1 liter = 1000 milliliters, express this volume in liters.
