Answer :
The density of a cement block with dimensions 2.00 cm x 2.00 cm x 9.00 cm and a mass of 108g is 3 g/cm³.
The question is asking to calculate the density of a cement block with dimensions 2.00 cm x 2.00 cm x 9.00 cm that has a mass of 108g. The density is defined as the mass per unit volume. So, we first need to calculate the volume of the block, which can be found using the formula for the volume of a rectangular solid: Volume = Length * Width * Height. Thus, Volume = 2.00 cm * 2.00 cm * 9.00 cm = 36.00 cm³. The density is then calculated by dividing the mass by the volume. Using the formula Density = Mass / Volume, we get Density = 108g / 36.00 cm³ = 3 g/cm³.
