If 24 g of material fills a cube 2 cm on a side, what is the density of the material?

The density of this material is

Explanation:

It is given that,

Mass of the material, m = 24 g = 0.024 kg

Side of the cube, a = 2 cm = 0.02 m

We need to find the density of the material. Density is given by mass per unit volume of the material i.e.

Volume of cube,

So, the density of this material is . Hence, this is the required solution.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
