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.

Assume that there are two cars for every three people, and each car has driven an average of 12,000 mi per year and the average car gets 15 miles per gallon.arrow_forwardA ton is a measure of volume frequently used in shipping,but that use requires some care because there are at least three types of tons: A displacement ton is equal to 7 barrels bulk, a freight ton is equal to 8 barrels bulk, and a register ton is equal to 20 barrels bulk. A barrel bulk is another measure of volume: 1 barrel bulk = 0.1415 m3. Suppose you spot a shipping order for “72 tons” of M&M candies, and you are certain that the client who sent the order intended “ton” to refer to volume (instead of weight or mass, as discussed in Chapter 5). If the client actually meant displacement tons, how many extra U.S. bushels of the candies will you erroneously ship if you interpret the order as (a)72 freight tons and (b)72 register tons?
