We have received a solid aluminum cylinder in need of rigging. The only information available is the material of the solid object, which is aluminum. We can calculate the weight of the object by multiplying the volume of the object, times the weight per volume, for aluminum ,from the weight chart. To calculate the volume we need to multiply pie, times the radius squared, times the height. Using our measuring tape we measure a radius of 2 feet, and a height of 6.5 feet. Using the measured values we then multiply the value of pie, which is 3.14, times 2 squared, times 6.5. This gives us a volume of 81.64 cubic feet. We can now multiply this volume value, times the weight per volume value from the chart. That is, we multiply 81.64 cubic feet, times 165 pounds per cubic feet, resulting in a weight for our solid aluminum cylinder of 13,470.6 pounds.
