How does one calculate thickness of an object?
« on: October 27, 2006, 05:43:33 PM »
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?

V = m * w * h

h =V/(m*h)

h = 0.26/(10.2*7.5)

This is of course assuming it is a square/rectangle, other wise the equation for volume is different.
