Answer: The density of solid is \(4.3g/cm^3\)
Explanation:
To calculate the volume of cuboid, we use the equation:
\(V=lbh\)
where,
V = volume of cuboid
l = length of cuboid = 5 cm
b = breadth of cuboid = 3 cm
h = height of cuboid = 2 cm
Putting values in above equation, we get:
\(V=5\times 3\times 2=30cm^3\)
To calculate density of a substance, we use the equation:
\(Density=\frac{Mass}{Volume}\)
Putting values in above equation, we get:
\(\text{Density of solid}=\frac{129g}{30cm^3}\\\\\text{Density of solid}=4.3g/cm^3\)
Hence, the density of solid is \(4.3g/cm^3\)
