Answer:
2535 cm²
Step-by-step explanation:
Part 1
Cube root the ratio to find the length factor as volume factor = length factor³
∛512 : ∛2197 = 8 : 13
Part 2
Square the ration as area factor = length factor²
8² : 13² = 64 : 169
Part 3
Apply the ratio
64 : 169
960 / 64 = 15
15 x 169 = 2535
14 / 21 = X/15 => X = 14 * 15 / 21 => divide by 7 => 2 * 15 / 3 => divide by 3 => 2 * 5 / 1 => 10
