  1. Determine tha important dimensions (length, width, height, diameter etc.) and what kind of a shape it is. Then use the appropriate formula to compute the volume, area or perimeter. For example, for a cylinder the perimeter is pi r^2.

    Areas and volumes cannot be measured directly with a linear scale.
