a mechanical pencil hass a mass of 47.4 grams. the volume of the pencil is 15.8 cubic centimeters. what is the density of the pencil
Density is defined as the mass of an object divided by its volume. To find the density of the mechanical pencil, we divide the mass (given as 47.4 grams) by the volume (given as 15.8 cubic centimeters).
Density = Mass / Volume
Density = 47.4 grams / 15.8 cubic centimeters
Density ≈ 3 grams per cubic centimeter.
To find the density of the mechanical pencil, you need to divide its mass by its volume.
Step 1: Convert the mass from grams to kilograms:
Since 1 kilogram (kg) is equal to 1000 grams (g), divide the mass by 1000:
47.4 grams ÷ 1000 = 0.0474 kg
Step 2: Calculate the density by dividing the mass by the volume:
Density = Mass / Volume
Density = 0.0474 kg / 15.8 cm³
Step 3: Perform the calculation:
Density = 0.003 kg/cm³
Therefore, the density of the mechanical pencil is 0.003 kg/cm³.
