Question

I bought a pack of 100 rectangular index cards. Each card measured 15 cm by 10 cm. The pack said: paper density=200gsm (grams per square metre). This means that a square metre of these cards weighs 200 g.

Each pack of cards is wrapped in a sheet of 50GSM paper with an area of 800cm^2. I have a number of packs and wish to store them on a shelf which cannot hold more than 10kg. What is the largest whole number of wrapped pack that can be stored?
