The density of the cube measuring 2 cm by 4 cm by 1 cm and with a mass of 8 g is 1 g/cm³ (option A)
Density calculation
The density of a material is simply the mass of the material per unit volume of the material. The density of a material is expressed mathematically as:
Density = mass / volume
Now, we shall calculate the volume of the cube. This is shown below:
- Dimension of cube = 2 cm × 4 cm × 1 cm
- Volume of cube =?
Volume of cube = Dimension of cube
= 2 cm × 4 cm × 1 cm
= 8 cm³
Finally, the density of the cube can be calculated as shown below:
- Volume of cube = 8 cm³
- Mass of cube = 8 g
- Density of cube = ?
Density of cube = Mass of cube / Volume of cube
= 8 / 8
= 1 g/cm³
Thus, the answer is option A
