I have a flat piece of metal with a density of 2.699 g/cm3. It has a mass of 0.69g, length of 10.2cm and width of 7.5cm. I've managed to calculate the volume of .26cm3 using the formula Density= mass/volume. (V=0.69/2.6999=.26cm3).
However, I'm stuck at how to calcuate the thickness. I have a formula: V = l x w x h (height has the same meaning as thickness for this purpose) so it would be .26cm3 = 10.2cm x 7.5cm x ? Do I multiply 10.2cm x 7.5cm then divide the sum by .26?
