Answer:
13-about 36 floors
14-remove 2 blocks from the taller building and add to the smaller building
15-D
Step-by-step explanation:
13- 509/14=36.357... so about 36 floors
14- one building is 2*2*4 and the other is 2*2*5, so removing 2 blocks from the tallest building would give them both equal volume. Volume of building 1 is 20 minus 2 is 18. Building 2 volume is 16 add 2 is 18. 18=18 so they're even
15- Volume of Q is 30 and Volume of R is 24 30+24 is 54
