Answer:
It is a mixed number because a fraction would be like 4/9.
Step-by-step explanation:
How you remember is that a decimal is in a place that makes it a mixed number,
For this case we have that by definition, the volume of a rectangular prism is given by:

Where:
It is the area of the base
h: It is the height
So:

The volume of the prism is:

Now, the volume of the cubes is:

Thus, we divide and find the number of cubes to fill the prism:

ANswer:
n = 2.5
1250 lbs of sand.
So first let's find the volume of the sand in the sandbox. You have a square sandbox, with a side length of 5, meaning you have a length and width of 5. You also have half a foot of sand in the sandbox, meaning that you have a height of 0.5. To find the volume of the sand, multiply the length by the width by the height:

So you have 12.5 cubic feet of sand. If each cubic foot of sand is 100 lbs, then you just multiply the two:
