Answer: The density of the cube of metal is \(8.91g/cm^3\)
Explanation:
To calculate the volume of cube, we use the formula:
\(V=a^3\)
where,
a = edge length of cube
Edge length of cube = 1.2 cm
Volume of cube = \((1.2)^3=1.728cm^3\)
To calculate density of a substance, we use the equation:
\(\text{Density}=\frac{\text{Mass}}{\text{Volume}}\)
We are given:
Mass of cube = 15.4 g
Volume of cube = \(1.728cm^3\)
Putting values in above equation, we get:
\(\text{Density}=\frac{15.4g}{1.728cm^3}=8.91g/cm^3\)
Hence, the density of the cube of metal is \(8.91g/cm^3\)
