Answer:
Maximum Volume = 29,659.5 cubic inches
Step-by-step explanation:
We can write the perimeter as 2*(x+h) and this is equal to 117
So

The volume is 
Plugging the expression for h, we have:

The max volume can be found when this differentiated is equal to 0, or dV/dx=0

x can't be 0, so we take x = 39
and thus h=58.5-x = 58.5-39=19.5
Max Volume = 
Yes! i’m really good at absolute value! wanna add me on snap?
The width is 12.8 and when u round it is 13 foot
Let x = Edna's age
then it follows that (x + 1) is Ellie's age and (x + 2) is Elsa's age
We can now write and equation for the sum of their ages equal to 108:
x + (x + 1) + (x +2) = 108 simplify the left side
3x + 3 = 108 subtract 3 from both sides
3x = 105 divide both sides by 3
x = 35
Edna is 35, Ellie is 36, and Elsa is 37
