The required details about density is mentioned in below paragraph.
How might you determine the wooden block's density?
A wooden block must first be weighed in order to determine its mass in grams before one can determine its density. Its length, breadth, and height can all be measured in centimeters (cm), and the volume can then be calculated as a unit of cubic meters (cm3). To get the density in g/cm3, we must divide the mass by the volume.
How can the mass be located?
Using a formula, one can estimate an object's mass based on weight. Weight (W) divided by the Gravitational Acceleration yields mass (M) (G). Find the weight in pounds that would be equivalent in Newtons.
