    We will first convert all units to meters and then solve the problem.

    We are given that:

    1000 mm = 1 m

    120 mm = ? meters

    using cross multiplication:

    120 mm = (120*1) / 1000 = 0.12 m

    Now, when the two objects are placed over each other, their total height is the result of summation of both heights, therefore:

    total height = 0.12 + 1.5 = 1.62 m

    Based on the above calculations, the correct choice is:

    b) 1.62 m
