A cubed-shape container has an edge length of 8 cm. The container is filled with decorative crystal cubes. Each cube has an edge of 1 cm and costs 5¢. What is the total cost of the crystal cubes in the container?

Answer 1

`\$25.60`

Explanation:

step 1

Find the volume of the container

The volume is equal to

`V=8^(3)=512\ cm^(3)`

step 2

Find the volume of the crystal cube

The volume is equal to

`V=1^(3)=1\ cm^(3)`

step 3

Find the total number of crystal cubes in the container

Divide the volume of the container by the volume of the crystal cube

so

`512/1=512\ crystal\ cubes`

step 4

Find the cost

Multiply the number of crystal cubes by $0.05

`512*0.05=\$25.60`
