Answer
a) $42.2\, cm^{3}$
b) $3.48\, cm$
c) $1.37\, in$
Work Step by Step
a) $\text{Volume}=\frac{\text{Mass}}{\text{Density}}=\frac{0.443\times10^{3}\,g}{10.5\,g/cm^{3}}$
$=42.2\,cm^{3}$
b) $\text{Volume}= (\text{Edge length}) ^{3}$
$\implies \text{Edge length}=\sqrt[3] {\text {Volume}}$
$=\sqrt[3] {42.2\, cm^{3}}=3.48\,cm$
c) $\text{Edge length}=3.48\, cm=3.48\, cm\times\frac{1\,in}{2.54\,cm}$
$=1.37\,in$
