Say you are an engineer or scientist. You also have found yourself having designed a dungeon for an RPG. In that dungeon is a room with an ancient game in a state of disarray. It seems like a game with similarities to chess and go. The whole room is the playing board and the pieces are giant.
How giant? They are perfect spheres which are ten feet in diameter (about three meters). They are made of different substances. They have been imbued with magical properties and can locomote magically. However some appear to be broken.
Given different materials, what do they weigh?
Clearly, you need to do some math. But you also need to do some research. You need the material density of the objects. You have dozens of the objects and they're all different. Math alone doesn't cut it. You need a calculator.
Originally this was written as a spreadsheet. Because that's both a great data storage source and a calculator. But that's not great for you. And I did most of the work already. So here you go. Because you'll have this exact question as me.
Don't trust people on the Internet even if they're talking about math. If you need this for some really important reason, please check the facts.
The density of some materials is variable. Sometimes highly. So before moving this over to this calculator, I got rid of my average values and used low and high density values. There are some wide ranges still. Caveat emptor.
