To find the density you need the mass and volume and then, density = mass/volume. Given a ruler, you can easily measure an edge of the cube. If that is x units, then the volume is x3 cubic units. However, it is not clear how you find a mass with just a balance. You need some standard weights, but these do not appear to be provided. You are stuck and cannot answer the question.
Postal scales come with different measurements. Some are more specific than others. If you do not need your scale to be very specific, you have the option of picking cheaper scales. Office supply stores like Staples and OfficeMax have these on sale sometimes.
Scales to measure its mass and a ruler to measure the length of the cube's side.
balance the reactant side with the product side of the equation.
You would need two and a half 400 gram weights to equal 1 kilogram.
You will need a pair of scales and some standard mass measures (weights).
There are many resources one has when purchasing a scale for their shop or business. Some of these include the Scale Shop, InScale Sales, and various food equipment retailers. Amazon and eBay also have an assortment of shop scales for purchase.
Weights which have been carefully measured and crafted for the specific purpose of calibrating scales should be used in scale calibration. These weights need to be of a known weight in order to adjust the scale.
You need balance. Weights equal to the weight of the workpiece on the holder.
Because without balance he would either fall over from being too top heavy or he would drop the weights.
You will need weights between increments of a gram (to 2 decimal places) and up to 100 grams. This is if you want to calibrate for the metric system.
They don't need scales
A beam balance scale is a precision instrument for measuring mass. They sell beam scales specifically for doctors, so it is probably used in a doctor's office.
the owners manual will usually have a curb weight - otherwise youll need to drive it onto a set of scales at a weigh station - call your nearest dealer - sometimes they need to record the weights with an empty gas tank for transportation tax purposes
You don't need to "do" weights, but most boxers do some strength training with weights!
There are several websites that offer certified gram scales. You can try http://www.discountscales.com/sub/halfgramscales.htm or http://www.toplinedigitalscales.com/. They run around $100 on average.
Electronic balances need no such known masses once they have been properly calibrated. Analytical balances are very accurate and until the advent of semiconductors were the only scales available.
