Calculating the density of solids is pretty simple! Here's a step-by-step guide on how to do it:

1. Measure the Mass: First, you need to find the mass of the object. You can use a balance scale to measure it in grams (g).

2. Find the Volume:

   • If the object has a regular shape, like a cube or a cylinder, you can use specific math formulas to find its volume.
   • For odd-shaped objects, you can use the water displacement method. This means you put the object in a container of water and see how much the water level goes up.

3. Calculate the Density: To find the density, use this formula:

   [ \text{Density} = \frac{\text{Mass}}{\text{Volume}} ]

Just plug in the numbers you've found, and you'll have your answer!
