40cm is 400mm
40cm times 40cm times 40cm equals 64,000cm. The volume of the cube is 64,000cm cubed or 0.064m cubed.

To make 500ml of 0.8M HCl solution from 10M HCl, you will need to dilute the 10M HCl solution. Calculate the volume of 10M HCl required to make 500ml of 0.8M solution using the dilution formula C1V1 = C2V2. Measure the required volume of 10M HCl, then add water to make up to a total volume of 500ml.
The perimeter is 40cm
