Felipe made a toy boat out of clay, but it kept sinking in water. He changed the boat's design by making it slightly wider than before. Why did Felipe's newly designed boat float on water?
A. He decreased the density by increasing the volume.
B. He decreased the density by decreasing the volume.
C. He increased the density by increasing the volume.
D. He increased the density by decreasing the volume.
I think its A
The answer is A.
You are correct! Felipe's newly designed boat floated on water because he decreased its density by increasing the volume.
To understand why this is the correct answer, let's take a look at the concept of density. Density is a measure of how much mass is contained in a given volume. When an object is placed in water, it floats if its density is lower than that of water. Conversely, it sinks if its density is higher than that of water.
By making the boat slightly wider, Felipe increased its volume while keeping the mass (amount of clay) the same. Since density is mass divided by volume, increasing the volume while keeping the mass constant results in a decrease in density. This decrease in density allowed the newly designed boat to float on water. So, option A is the correct answer.
