100 g20 mL = 5 g/mlVolumeWhat is the formula for volume? Length x width x heightWhat are the 3 ways you can express volume?If it is a liquid, or measured in a liquid, you can use liters (mL, L, kL). Since liquids already imply filling up a height you dont need the 3 exponent.If the object is a solid, and you can use a meter stick, then you have to use the 3 exponent.If the object is small, like medicine in a shot, you can use cc (cubic centimeters.) This already says cube, so you dont need the 3 exponent.Volume QuestionsFormula for volume? ___________________________What is the correct ending units: 6 g 6 g3 cm = 2 ___ 3 mL = 2_____
