Answer:

Step-by-step explanation:

Given that the height of a rectangular box is 2 times its length, and its width is 3ft more than its length

Let us assume length = x then height = 2x and width = x+3

Now volume = lwh = x(x+3)(2x) = 68

Simplify to get

2x^3+6x^2 -68 =0

Using graphing calculator we find that x = 2.489

i.e. x= 2.49 ft after rounding off to two decimal places

Length = 2.49 ft.
