Three-quarters 37241

We have two cube-shaped tanks. The first has an edge of 12 dm long, and the second has an edge of 20% longer. By what % more or less water is there in the second tank if the first is three-quarters full and the second three-eighths full?

Correct answer:

p =  -13.6 %

Step-by-step explanation:

a=12 dm q=100%+20%=1+10020=1.2 b=q a=56 12=56 12=572=14.4 dm  V1=a3=123=1728 dm3 V2=b3=5723=2985.984 dm3  V11=43 V1=43 1728=43 1728=45184=1296 dm3 V22=83 V2=83 125373248=8 1253 373248=10001119744=1119.744 dm3  p=100 V11V22V11=100 12961251399681296=568%=13.6%
