Answer 4

bottom volume = ACD,
top volume = DBA

do you understand why?

Answer 5

Yes you split each shape up

Answer 6

correct, and since you're given each value you can plug in the numbers and add the bottom to the top, that'll be your answer

Answer 7

Can you give me the formulas?

Answer 8

area of bottom + area of top = total area

area of bottom = ACD
area of top = DBA

Answer 9

*replace the word area with volume

Answer 10

So your saying for the area of bottom and top you multiply ACD as bottom then add that to area of top DBA?
