Final answer:
The density of the wooden block, which has a mass of 27 grams and a volume of 27 cubic centimeters, is 1 gram per cubic centimeter.
Step-by-step explanation:
The density of an object is calculated by dividing the mass of the object by its volume. The formula to find density is density = mass / volume. Given that a wooden block with a mass of 27 grams has a volume of 27 cubic centimeters (since the block is 3.0 cm on each side and the volume of a cube is the side length cubed), we can determine its density.
To find the density, we use the formula:
density = mass (g) / volume (cm³)
Substitute the given values:
density = 27 g / 27 cm³
Upon calculating, we obtain:
density = 1 g/cm³
Therefore, the density of the wooden block is 1 gram per cubic centimeter.
