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
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.
