2.My 1967 Encyclopædia Britannica says that Lake Erie has a surface area of 9930 square miles and an average depth of 58 feet. How much water does it hold, in cubic miles? in liters?
(1 mi = 5280 ft; 1 liter = 0.001 m³, and use the answer to the previous problem.)

3.Lake Erie has a surface area of 9930 square miles. If an inch of rain falls on the lake one day, how many gallons have been added to its volume? How many liters?

  1. 1. (1609.344)^3 = ?

    2. volume in miles = 9930 * 58/5280 = ? cubic miles

    Above answer times answer to #1 = volume in meters

    Volume in meters *.001 = ? liters

    I'll leave the last one for you. Use similar processes that were used in the first two problems.
