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.
My answer is D

Hello @Ms.Sue can you please help me
It's A
thank you
Of course! I'd be happy to explain the correct answer to you.
When an object floats on water, it means that the object's density is less than the density of the water. Density is the measure of how much mass is packed into a given volume. In simpler terms, it's how heavy an object is based on its size.
To understand why Felipe's newly designed boat floats on water, we need to consider the principle of buoyancy. According to Archimedes’ principle, the buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid displaced by the object. In other words, if the weight of the water that the object displaces is greater than the weight of the object itself, the object will float.
By making his boat slightly wider, Felipe increased the volume of the boat while keeping the mass the same. This means that he decreased the density of the boat. Density is calculated by dividing mass by volume. So if we decrease the volume while keeping the mass the same, the overall density decreases.
In this case, Felipe increased the volume of the boat and kept the mass the same. Therefore, the correct answer is A. By increasing the volume and keeping the mass constant, Felipe decreased the density of the boat. As a result, the boat floated on water instead of sinking.
I hope this helps clarify the concept for you! Let me know if you have any more questions.
