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!
Step-by-step Explanation:
First find out what is the price after 30% off.
250 · 0.3 = 75
250 - 75 = 175
Then find the tax and add it on. Remember to calculate the tax AFTER the discount.
175 · 0.06 = 10.50
175 + 10.50 = 185.50
