Linear Measure Ratio: a:b
Area Ratio: a^2:b^2
Volume Ratio: a^3:b^3

"879 cm2 and 220 cm2"

879:220 ==> 29.648^2: 14.8324^2

29.648^3:14.8324^3 ==> 26,060.534:3,263.127

Can you answer the question?

I'm still really confused. Sorry :/

I found the square roots in order to determine a and b.
I used a and b to determine a^3 and b^3.  This gives the ratios of the volumes.
