Answer:
<em>Steve has 54 Duos</em>
Step-by-step explanation:
<u>Proportions</u>
It's given three duos (D) is worth as two trios (T), i.e.:
3D = 2T
Steve has 36 trios, that is, 36T. To find the equivalence to duos, we multiply the given relationship by 18:
18*3D = 18*2T
Operating:
54D = 36T
Therefore, 36 trios are equivalent to 54 duos.

Answer:
the third one
Step-by-step explanation:
To solve the problem we must set the equation for the volume and surface area
let x be the side of the square base
and h be the height of the box
so the volume , v = hx^2
and the area, a = x^2 + xh = 56
then solve for the equation of h
x^2 + xh = 56
xh = 56 - x^2
h = 56/x - x
to solve the maximum volume, solve the first derivative of the volume and equate to zero
v = hx^2
v = (56/x - x) x^2
v = 56x - x^3
dv/dx = 56 - 3x^2
0 = 56 - 3x^2
3x^2 = 56
x = 4.32 ft
h = 8.64 ft
