Density = mass / volume

To calculate the density of the solid sample

you need to calculate the mass and the volume

the mass before the block was added was 68.4 grams and then after the block was added, the scale shows 86.8 grams

so the mass of the block is going to be 86.8 - 68.4

similarly, to find the volume look at the graduated cylinder

the water level initially at 23 mL but after adding the block, it becomes 36 mL

so what is the change in the volume? just subtract

and now that you have the mass and the volume, use the formula

density = mass / volume
