It is a geometric sequence
Ok, so what we want to do here is first remove the repeating decimal.
x=2.16 repeating
10x=21.6 repeating
100x=216.6 repeating
Subtract 10x=21.6 repeating from 100x=216.6 repeating. This will get rid of the repeating numbers.
100x=216.6 repeating
-10x=21.6 repeating

90x=195
Divide both sides by 90.
x=195/90
Now you can simplify that into 13/6.
Answer:
5.5 cu ft vol = L*w*h* w=x L= 3x h=3
270= 3[3x*x]
The correct answer is 58/7 (decimal: 8,28....)
I think the answer would be B that’s the only one I consider
