How is weight load capacity calculated? How-To Calculate Load Weight: example 1—steel sheet/block

1. Calculate the weight of a steel plate (shown in figure 1) 2ft wide X 5ftlong X 1inch (0.0833ft) thick.
2. Use the formula:
3. Volume = Length X Width X Height.
4. Unit weight of steel is 490 lbs/ft³
