Lxxxi is a Roman numeral that represents the number 81.
The volume of 81 grams of aluminum can be calculated using its density, which is 2.7 g/cm^3. By dividing the mass (81 grams) by the density (2.7 g/cm^3), you can find that the volume of 81 grams of aluminum is approximately 30 cm^3.
A centimetre is a measure of length in 1-dimensional space so nothing can have a volume of 30 cm.A block of aluminium, with a volume of 30 cubiccentimetres, has a mass of 81 grams.

The density of the rock is calculated by dividing the mass (35 grams) by the volume (7.0 cubic centimeters). So, the density would be 5 grams per cubic centimeter.
To convert densities given in g/mL to kg/L, you need to divide by 1000. For example, 1 g/mL is equal to 0.001 kg/L. When comparing densities, the numerics will remain the same between g/mL and kg/L, but the units will be different - g/mL versus kg/L.
Earth has about 50 times the volume of the Moon (and 81 times the mass of the Moon).
The volume of the Moon is 2% compared to the Earth. You would need 81 objects with the mass of the Moon to match the mass of the Earth.
