Question

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 increasing the volume.

Answer 1

The answer is A because the boat is being spread out which increases the total amount of space, or volume. The density is decreasing because the same amount of clay is being spread out over a wider surface. (Density is mass/volume and the mass is still the same but the volume has become smaller so that means that the density is also smaller)

Answer 2

Increased surface area so it was easier to float
