Question

Malika wants to build a toy raft that will float in water. She has a few materials to choose from. She takes a sample of each of these materials and measures their mass and volume. She records her measurements in a chart as shown. Which of these materials can Malika use to build her raft? a.glass, cork, and lucite

b.pumice, rubber, and cedar
c.rubber, glass, and lucite
d.pumice, cedar, and cork

Answer 1

Is there a visual to this question? It seems to be a density question. To figure out which items Makila should use to build her raft, use the 3 items that have a density less than that of water. Water has a density of 1 g/cm^3 so anything less that will float. If they only give you mass and volume in the chart, remember that Density = mass / volume. I hope this helps you!
