Answer :
The density of a piece of aluminum metal with height = 1.38 cm, length =
2.80 cm, width = 4.02 cm and mass 41.93 g is 2.70 g/cm³.
What is density?
Density of a substance is the mass per volume of the substance. Thus mathematically it can be written as:
Density = mass/volume.
Density of a substance depends on the mass, volume, temperature, pressure and bond type of the substance.
It is given the height, length and width of the metallic piece and its volume can be calculated by multiplying these dimensions.
Volume = 2.80 × 4.02 × 1.38 cm
= 15.533 cm³.
The density of Al piece is calculated as follows:
Density = 41.93 g / 15.533 cm³
= 2.70 g/ cm³.
Hence, density of the piece of aluminum is 2.70 g/ cm³.
