    Answer:

    I will answer this in English.

    He has 45 years.

    a year has 365 days.

    a day has 24 hours.

    So he has:

    45*365*24  hours = 394,200 hours.

    His mass is 78 kg,

    And we know that 1 slug = 1lbf*ft/s^2

    Then, the first step is transform the 78 kg into lbf.

    1kg = 2.2 lbf.

    then 78kg = 78*2.2 lbf = 171.6lbf.

    Now, the weight is m*g, where m is the mass and g is the gravitational acceleration, in this case the gravitational acceleration in ft/s^2 is:

    g =  32.2 ft/s^2

    Then the weight in slugs is:

    W = 32.2ft/s^2*171.6lbf = 5,525.5 slugs
