Question

Suppose you have two 100-mL graduated cylinders. In each cylinder there is 40.0mL of water. You also have two cubes: one is lead, and the other is aluminum. Each cube measures 3.0cm on each side. After you carefully lower each cube into the water of its own cylinder, what will the new water level be in each of the cylinders?

Answer 1

67 mL

Step-by-step explanation:

In each cylinder there is 40.0 mL of water.

volume of each cube = L × L × L = 3 cm × 3 cm × 3 cm = 27 cm³

when a substance is suspended in a liquid, the substance will displaced liquid equal to its own volume.

1 cm³ = 1 ml

27 cm³ = 27 mL

the new water level equal = 40.0 mL + 27 mL = 67 mL in each cylinders
