V = k x^3
A = c x^2
for big one xb^3 = 1331/k
for small one xs^3 = 216/k
or
xb/xs = (1331/216)^(1/3)= 1.83333333....
so
xb^2/xs^2 = area ratio = 3.361111....
484/3.361111... = 144
The volumes of two similar solids are 1,331 m^3 and 216 m^3. The surface area of the larger solid is 484 m^2. What is the surface area of the smaller solid?
A. 864m^2
B. 288m^2
C. 144m^2
D. 68m^2
I think the answer is B or C just a lil confused...

Im pretty sure 17 is actually 1:8, instead of 1:4
(The answers switch up all the time btw so the questions may be a little different)
