1. Density Using Volume to Calculate Weight Density = Weight / Volume
The DENSITY of a material is expressed as the weight of the material per unit of volume.
Density = Weight / Volume
Weight = Density x Volume
Material Density lbs./ft3
Aluminum 168.5
Steel 489
Water 62.4
Air

2. Calculate the Weight of the 6” x 9” Plate
Corner Radius =0.250”
= 3.14
8.688”
Plate Thickness 0.090”
Hole Dia ”
Check your calculations by weighing the plate!
5.688”
Note: The solution to this problem is dependent on calculating the Volume accurately!
Density of Al = (approximately) 1.56 oz/ in3
