Answer:
Amount of calories in that butter is 4500cal
Explanation:
It's relatively simple:
You already have energy density(energy divided by mass)
You already have butter density (mass divided by volume)
And you have dimensions of that butter
From those dimensions (5cmx5cmx20cm) you can calculate the volume, which is 500cm³. Then, using that volume you can calculate the mass (density = mass / volume, which means that <em>mass = density * volume</em>) and that is 450g. Now that you have the mass, you can calculate the amount of calories in that butter (energy density = energy/mass, which means that <em>energy = mass * energy density</em>) and that is 4500cal.
D) decreasing blood viscosity as blood will be lighter and easily movable hence an increase in blood flow
