Answer:
8 : 343
Step-by-step explanation:
Given 2 similar figures
ratio of sides = a : b, then
ratio of volumes = a³ : b³
Here the ratio of edges = 2 : 7, hence
ratio of volumes = 2³ : 7³ = 8 : 343
It says to simplify so number 3 would be 12

Number 4 is

Number 5 is
X-0.20x=5.56
Solve for x
So the original price is
X=6.95
