Answer 2

Mass of the gold bar = 13.896‬ kg

Step-by-step explanation:

see attached figure :

Volume of gold Bar  = ( Trapezium cross sectional area ) * Length

=  ((1/2)(12 + 6) * 5)  * 16

= 45 * 16

= 720 cm³

Density = 19.3  g/cm³

Density = Mass /Volume

=> Mass = Density * Volume

=> Mass = 19.3 * 720

=> Mass = 13,896‬ g

=>  Mass = 13.896‬ kg

Mass of the gold bar = 13.896‬ kg
