To find the mass, first convert the dimensions from inches to centimeters (1 inch = 2.54 cm). Then calculate the volume in cm³ and multiply by the density of gold. The volume is 10.0 in × 4.00 in × 3.00 in = 120 in³. Converting to cm³ gives 120 in³ × (2.54 cm/in)³ = 1966.08 cm³. The mass is then 1966.08 cm³ × 19.3 g/cm³ = 3.80 × 10⁴ g.
