the density of the block is 7.7 g/cm^3.
To calculate the density of the block, you need to divide its mass by its volume. You can calculate the volume of the block by multiplying its length, width, and height: 4 cm * 2 cm * 3 cm = 24 cm^3.
Then, you can divide the mass of the block by its volume to calculate its density: 185 g / 24 cm^3 = 7.7 g/cm^3.
