What are area models?
An astronaut uses water displacement to find the volume of a rock sample. This astronaut knows that the amount of water that rises in the graduated cylinder is equal to the volume of the rock sample. This technique works because of the relationship between milliliters and cubic centimeters, when measuring volume.
What is 1 mL = 1 cu cm?
