Solve the following questions:
Question I: Compute the order of magnitude of the mass of a bathtub half full of water. (Assume the tub measures 1.3 m by 0.5 m by 0.3 m.)
Question II: Compute the order of magnitude of the mass of a bathtub half full of pennies. (Assume the pennies are made entirely of copper.)
I need help to solve the above questions.
