Answer:
The length will be 5 feet, width will be 4 feet.
Step-by-step explanation:
Given:
volume of the box = 40 ft^3
Length of the box = (2x-1)ft
Width of the box = (3x-5)ft
Height of the box = 2ft,
To Find:
The length and width of the box = ?
Solution:
We know that,
-----------------------(1)
Solving eq(1) by quadratic equation formula
Substituting the values
x = 3 x =-0.833
Neglecting the negative value,
we have x = 3
Then the length will be
(2(3)-1) = (6-1) =5 ft
The Width will be
(3(3)-5) = (9-5) = 4 ft
