How are linear units square units and cubic units different? - Answers

Lines are measured with lines. For example, the length of a road is measured with standard lines (linear units) such as yards, miles, meters or kilometers. Areas are measured with areas. A field is measured with standard areas (usually square units) such as square yards, square miles, or square kiometers. Volumes are measured with volumes. A container is measured with standard volumes (often cubic units) such as square inches or square centimeters. Look out for calculations involving linear, square and cubic units. For example, a square measuring three inches on the side has an area of 3 x 3 = 9 square inches. A cubical tank measuring five meters on each side has a volume of 5 x 5 x 5 = 125 cubic meters.
