The correct answer is 0.72 g/cm3
Explanation:
The density of a material depends on both its mass (amount of matter), which is usually provided in grams (g), and its volume (space occupied), which is provided in units such as cubic centimeters cm3. Moreover, to find how dense the material is, take the mass and divide it into the volume. The process for finding the density of the block of wood is shown below:
This means the density is 0.71g/cm3 and this can be rounded to 0.72 g/cm3
