Your teacher measures the mass of a block of clay at 300 grams on a triple beam balance. He cuts some clay from the block. Explain how the mass will change.

• The mass of the block of clay will be greater because there is more material.

• The mass of the block of clay will be greater because there is less material.

• The mass of the block of clay will be less because there is more material.

• The mass of the block of clay will be less because there is less material.
