Question

Which two of the following are the densest of the materials shown?

Material Mass (g) Volume (L)

Rock 1000 0.5

Pillow 200 10

Bottle of soda 2000 2

Loaf of bread 100 1


rock and bottle of soda

loaf of bread and rock

loaf of bread and pillow

bottle of soda and loaf of bread

Answer 1

Step-by-step explanation:

The density of the material is given by,

Density =
`(mass)/(Volume)`

Case 1: Rock

Density =
`(mass)/(Volume)`

Density =
`(1000)/(0.5)`

Density = 2000
`(g)/(L)`

Case 2: Pillow

Density =
`(mass)/(Volume)`

Density =
`(200)/(10)`

Density = 20
`(g)/(L)`

Case 3: Bottle of Soda

Density =
`(mass)/(Volume)`

Density =
`(2000)/(2)`

Density = 1000
`(g)/(L)`

Case 4: Load of bread

Density =
`(mass)/(Volume)`

Density =
`(100)/(1)`

Density = 100
`(g)/(L)`

Thus, rock and bottle of soda has maximum density.
