American hydraulic engineers often use acre-feet to measure volume of water. An acre-foot is the amount of water that will cover an acre of flat land to 1 foot. Say 5 . 00 in of rain fell on a plain of 50 . 0 km 2 . How many acre-feet of water fell? Note 1 square mile equals 640 acres and 1 km = 0 . 6214 mi. HINTS: First, find the volume in the hybrid units of inch-km 2 and then use a separate factor of unity for each unit conversion: divide and conquer. a) 1066 acre-feet. b) 1492 acre-feet. c) 1776 acre-feet. d) 5150 acre-feet. e) 2470 acre-feet. 001 qmult 10520 1 4 5 easy deducto-memory: Fermi on lectures and the micro-century fullmult Extra keywords: mathematical physics 62.
