How should you find the volume of that rectangular block? You do know how to calculate the volume of a cube or rectangular box, right?

And density is just mass per volume. So once you have the volume in cubic cm, you can calculate the density in grams per cubic cm. Give it a go and show your work (and keep showing the units in your calculations to help keep things straight)...

To find the volume of the block, we can use the formula V = l x w x h, where l, w, and h represent the length, width, and height of the block respectively. In this case, the volume would be 2.9cm x 3.5cm x 10.0cm = 101.5 cm^3.

To calculate the density of the block, we can use the formula D = m/V, where m represents the mass and V represents the volume. In this case, the density would be 615.0 g/101.5 cm^3 = 6.06 g/cm^3.

It is important to note that the units for both volume and density must be consistent in order to get an accurate result. In this case, we used centimeters for both length and width, and centimeters cubed for volume. Similarly, we used grams for mass and grams per cubic centimeter for density. This allows for a proper comparison and understanding of the block's physical properties.
