d = M/V, where d is density, M is mass, and V is volume, is the formula for density. Grams per cubic centimeter are a typical unit of measurement for density.
To fill the graduated cylinder to the 2.0 mL mark, add water. The water makes a curve if you see the graduated cylinder from the side. Make sure the 2.0 mL level is at the bottom of the curve. Calculate the graduated cylinder's mass and the water's mass in milliliters using the gram scale. In the table, note the mass. Subtract the graduated cylinder's mass to determine the mass of 2.0 mL of water. To find and note the mass of 4.0 mL of water, repeat this procedure.

Explanation:
It is given that,
Displacement of the delivery truck, (due east)
Then the truck moves, (due south)
Let d is the magnitude of the truck’s displacement from the warehouse. The net displacement is given by :
d = 4.03 km
Let is the direction of the truck’s displacement from the warehouse from south of east.
So, the magnitude and direction of the truck’s displacement from the warehouse is 4.03 km, 37.4° south of east.
