Camp Nirvana sent a warning message over the CB radio. The Glass Skulls are patrolling the roadways and only allowing passage with a payment of 100 kg glass. The latest report stated there would be a possible run in every 400 miles. Your team has some solid glass blocks to use as bribe “money”. If the density of glass is 2500 kg per cubic meter and the blocks are 6 inch cubes, how many blocks should you take on your trip to ensure you have enough glass?
