Answer 2

The mass of gold bar is 926.4 kilograms

Given - Density and dimensions

Find - Mass

Solution - The density is related to mass by the formula -

Density = mass ÷ volume

Calculating volume by the formula -

Volume = length×breadth×height

Volume = 6×4×2

Performing multiplication and division of the volume of gold bar

Volume = 48 cm³

Keep the values in formula to find the value of mass of gold bar

Mass = density × volume

Mass = 19.3 × 48

Performing multiplication to find the value of mass of gold bar

Mass = 926.4 kilograms

Hence, the mass of gold bar is 926.4 kilograms.
