The least common multiple is 504
Answer:
150 square inches
Step-by-step explanation:
The surface area is the exposed area, which would be 6 sides with an area of 25 and 25x6 is 150

153/18=8.5
which means that Sarah can buy 8 new CDs and will have
153 - 8*18=9 dollars spare.
Sarah has extra cash because with that spare money she can't buy whole new CD.
8.67 (rounded to the nearest tenth)
