1. The volume of the container shown in the figure attached, is:
V=(5 in)(4.5 in)(3 in)
V=67. 5 in³
2. The problem says that the container is filled with sand to a height of 2.25 inches. Then, the volume of the sand into the container is:
V=(5 in)(4.5 in)(2.25 in)
V=50.62 in³
3. Therefore, you have:
67.5 in³----100%
50.62 in³---x
x=50.62x100/67.5
x=74.99%
What percentage of the container is filled with sand?
The answer is: 74.99%
