    You got me confused.

    5*3*3*1.6*3000

    is the same as

    [(5*1.6) + (3*1.6) + (3*1.6)]*3000

      5*3*3*1.6 is not the same as (5*1.6)*(3*1.6)*(3*1.6), however

      The reason we multiply with 1.6 on every dimension is because the ruler we use is 1.6m long. We effectively create a new unit, and have to convert. If a length is 5 person wide, then in reality it’s 5*1.6 = 8 meters long, where 1.6 is the conversion ratio from the unit of ‘person’ to the unit of ‘meter’. And this applies for every individual measurement.

      Also, 5*3*3*1.6 is not the same as (5*1.6)+(3*1.6)+(3*1.6) in the first place
