(2) Measuring Units: • 1 meter = 100 centimeter. • Mass measuring units are Gram - Kilogram. • 1 kilogram = 1000 gram. Exercise: 3- volume: Measuring tools -measuring units: • Liquid volumes measuring unit is: Liter or milliliter Liter = 1000 milliliter or = 1000cm3 • Solid volumes measuring unit is The Cubic meter (m3) or the cubic Centimeter (cm3). Estimating volumes of solid objects: Solid objects may be regular or irregular in shape: Calculating the volume of a regular shaped solid object: Like your science book, regular box Volume of cuboid = height × Width × Length · Estimating Volumes of irregular shaped solid objects Like piece of stone • Liquid volumes measuring unit is: liter or milliliter Liter = 1000 milliliter or = 1000cm3 • Solid volumes measuring unit is the Cubic meter (m3) or the cubic centimeter (cm3). |
