To calculate the density of a piece of concrete, we need to use the formula: Density = mass/volume. This formula helps us find out how tightly packed the particles in the concrete are.
Let's break it down: Density is like how many Lego blocks fit into a specific space. If you have a small box and can squeeze a lot of Legos inside, the density is high. If you have a big box with only a few Legos, the density is low.
In this case, the mass of our concrete is 522 grams. Think of this as how heavy the concrete is when you hold it in your hand. The volume is 232 cubic centimeters, which is like how much space the concrete takes up.
Now, we divide the mass by the volume: Density = 522g / 232cm³ ≈ 2.25 g/cm³. This means for every cubic centimeter of concrete, there are 2.25 grams of mass.
So, the density of the concrete is 2.25 grams per cubic centimeter. This tells us how compact or heavy the concrete is in a specific volume. If you understand this, you've mastered how to find the density of any object!
