I'm only answering because the app told me i need to help someone before I can ask another question, but I can't help because I don't know what to help you with so
To find the value of f(3) we need to follow the below steps :
Step 1 : First plot the graph of f(x)
Step 2 : We need to find f(3) or the function value at x = 3 therefore, in the graph locate the point (3,0)
Step 3 : Draw a line parallel to Y-axis passing through the point (3,0) .
Step 4 : Now there exists two cases :
If the drawn line do not intersect the graph of f(x), then no value of f(3) exists for the given function of x
If the drawn line intersects the graph, then the intersection point is marked and a line parallel to x - axis is drawn passing through that marked or intersection point. And the line where it intersects the y - axis is our required value of f(3).
If this is wrong than I guess I wasn't smart enough :)

Umm... I don't know.... Sorry.....
Answer:
Step-by-step explanation:
We will be able to fill the glass up to the amount of water possible to hold in the glass, minus the amount in the cube. This means it will be able to hold 
cubic cm of water.
Using the difference of cubes formula(you can prove this by expanding back out again), we get that 
Therefore, the answer is 
cubic centimeters and we're done!
