Answer:
length: x cm
width: x - 12 cm
height: 5 cm
Volume = L*W*H = 5x(x-12) = (5x2 - 60x) cm3
The box can hold "AT MOST" 1900 cm meaning it can hold from 0 to 1900 cm3 giving us:
5x2 - 60x ≤ 1900
Factoring out a 5 this can be written as: x2 - 12x ≤ 380
Working this as a quadratic to find the maximum dimensions:
x2 - 12x - 380 = 0
x = [12 ±√((-12)2-4(1)(-380))]/2
x = (12±√1664)/2
x = (12 ±40.792)/2
x = 6 ± 20.396
Discarding the negative:
x = 26.396 cm length
x-12 = 14.396 cm width
height = 5 cm
volume: LWH = 26.396(14.396)(5) = 1899.98 ≅ 1900 cm3
