Use a measuring cup. Back How would you find the volume of a toy box? Multiply the length, height and width. Back If you pour a pitcher of tea into 12 cups does the volume change? Explain The volume stays the same because we didn’t lose any liquid. Back Suppose you buy a toy that comes in a box. You take the toy out of the box to play with it. How does the mass and volume of the box compare before and after you take the toy out? The of the box would be the same. The mass of the box would go down when you take the toy out.
