1. Stars originate within clouds of gas and dust referred to as nebulas. 2. These clouds are drawn together by gravitational forces. 3. Once sufficient heat and pressure accumulate, nuclear fusion commences, representing the birth of a star.
Response: The volume of the cube that is underwater is 29.8 mL
Clarification:
Initially, we need to find the mass of the ice.
Equation applied:

Provided information:
Ice density = 
Volume of ice = 45.0 mL


The cube displaces 40.5 g of liquid to float.
Next, we will ascertain how much of the cube is submerged in the liquid.



Therefore, the submerged portion of the cube is 29.8 mL
