A copper bar has a mass of 1900 g and a volume of . Calculate the density of the copper bar.

A metal block has a mass of 10009 and has dimensions of 7.5 cm by 6 cm by 10 cm . Use this information to find the density of the metal block.

To calculate the density of the copper bar, use the formula . Here, the mass is 1900 g and the volume is 675 cm³. So, the density of the copper bar is:

Now, for the metal block, first calculate the volume by multiplying the dimensions:

Using the mass of 1000 g, the density is:

Super cool, right? Density is all about how compact a substance is. Copper, being a metal, has a relatively high density because its atoms are tightly packed. This means if you’re carrying around a copper bar, you’re also hauling a hefty chunk of material – a solid conversation starter at parties!

Now, you might wonder about where else density matters in everyday life. Think about how ships made of steel can float while icebergs (less dense than water) bob along in oceans. Getting a grasp on density helps in all sorts of practical situations, like designing boats or analyzing why certain substances mix or separate. It’s all around us, just waiting for you to notice!
