Answer: The mass of gold is 2316 grams.
Explanation:
To calculate the volume of cuboid, we use the equation:
[tex]V=lbh[/tex]
where,
V = volume of cuboid
l = length of cuboid = 10 cm
b = breadth of cuboid = 4 cm
h = height of cuboid = 3 cm
Putting values in above equation, we get:
[tex]V=10\times 4\times 3=120cm^3[/tex]
To calculate mass of a substance, we use the equation:
[tex]Density=\frac{Mass}{Volume}[/tex]
Putting values in above equation, we get:
[tex]19.3g/cm^3=\frac{\text{Mass of Gold}}{120cm^3}\\\\\text{Mass of osmium}=2316g[/tex]
Hence, the mass of gold is 2316 grams.
