Answer:

width = 5 in

length = 5+4=9 in

height = 2(5)= 10 in

Step-by-step explanation:

A gift box has a volume of 450 cubic inches.

Let 'w' be the width of the box

The width of the box is 4 inches less than the length.

$length = w+4$

The height is twice the width.

$height = 2 \cdot width$

height = 2w

Volume of box = length times width times height

$V=(w+4)(w)(2w)$

$450=(w+4)(w)(2w)$

$450=2w^3+8w^2$

$2w^3+8w^2-450=0$

$\quad 2\left(w-5\right)\left(w^2+9w+45\right)=0$

$w-5=0$

w=5

$\quad\left(w^2+9w+45\right)=0$ , this gives two complex values

so width = 5

length = 5+4=9

height = 2(5)= 10
