Paperweight
I bought a pack of 100 rectangular index cards. Each card measured 15 by 10 cm. The pack said ：Paper Density = 200 GSM (grams per square meter). This means that a square meter of those cards weighs 200 g.
A) All of the cards in the pack are place flat on a table without overlap. In square meters, what is the total area of the table covered by the cards?
B) Each pack of cards is wrapped in a sheet of 50 GSM paper with an area of 800cm squared. I have a number of packs and wish to store them on a shelf that cannot hold more than 10 kg. What is the largest whole number of wrapped packs that can be stored?
C) The total weight of 500 identical sheets of paper is 2.4kg. If each sheet measures 30cm by 20cm, what is its paper density in GSM?
D) A business card measures 55mm by 90mm. Its paper density is 300 GSM. Fins its exact weight in grams.

Hydraulic engineers in the United States often use, as a units of volume of water, the acre-foot, defined as the volume of water that will cover 1 acre (where 1 acre = 43560 ft2) of land to a depth of 1 ft. A severe thunderstorm dumped 2.9 in. of rain in 30 min on a town of area 36 km2. What volume of water, in acre-feet, fell on the town?
