Answer:
221g is the mass of the bar of aluminum
Explanation:
The volume of a bar of aluminum is obtained as:
Length*Width*height = Volume
That means the volume of the bar is:
2.03cm * 3.0056cm * 13.4cm = 81.8cm³
Now, the density of 2.70g/cm³ means the aluminum weighs 2.70g per cm³. The mass of 81.8cm³ is:
81.8cm³ * (2.70g / 1cm³) =
<h3>221g is the mass of the bar of aluminum</h3>
