A student need to predict the mass of a block of aluminum. The block is 4.23 cm on all sides and the density of aluminum is 2.7 g/cm3. What will the mass of the block be?
The equation for density is: Density = mass / volume. To rearrange for mass, you would times by volume on both sides to give you: Mass = density x volume Mass = 2.7 x (4.23^3) = 2.7 x 75.686967 = 204.3548109 = 204.35 g (to 2 dp)
