Learn how to calculate the density of a stainless steel knife using simple steps and examples. Perfect for beginners and children!
Imagine you have a shiny stainless steel knife in your hand. Now, let's pretend it's a little bit heavy and when you hold it, it feels weighty. That heaviness is its mass - like how much stuff is in the knife. Imagine taking a big measuring cup and filling it with tiny cubes until it's packed full. That's what volume is - how much space the knife takes up.
Now, density is a special math word that helps us understand how tightly packed something is. To find the density of the knife, we need to do a little math. First, we need to know the mass of the knife - it's like checking how heavy it is on a scale. In this case, the knife's mass is 20.4 grams, which is like saying it weighs 20.4 little cubes.
Next, we have to find the volume of the knife. Think of it as measuring how much space the knife takes up. In this case, the knife's volume is 2.55 cubic centimeters. That's like saying the knife fills a little box that's 2.55 cubes wide, tall, and deep.
Now, to find the density, we divide the mass of the knife by its volume. So, we take 20.4 grams (mass) and divide it by 2.55 cubic centimeters (volume). When we do the math, the density of the stainless steel knife is 8.00 grams per cubic centimeter. This means that in every cubic centimeter of the knife, there are 8 grams of stuff packed in tightly.
So, to summarize, density helps us understand how closely packed something is. For the stainless steel knife example, its density is 8.00 grams per cubic centimeter, showing us how much stuff is squeezed into each little space. Next time you hold a heavy object, think about its mass, volume, and density to better understand how compact and heavy it is!
