Answer:
Smallest number is 18. Largest number is 30.
Step-by-step explanation:
a:b:c = 4:5:3
∃x such that a = 4x, b = 5x, c = 3x
"sum of the numbers is 72"
a+b+c = 4x+5x+3x = 72
x = 6
a = 4x = 24
b = 5x = 30
c = 3x = 18
M = Undefined (because the line is perfectly vertical)
2*3*6 for large, 2*2*6 for med, 2*2*3 for small with 72 square cm as the surface area
