  1. _______ ___________ A student measures a bar of soap with a length of 8 cm, a width of 5 cm, and a height of 2.5 cm. The soap has a mass of 90 grams. What is the density ρ of the soap?
  2. ______________ Will the soap above float or sink?

    The graph shows volume and mass data gathered for slabs of a bar of soap.
