Answer:
- Given below.
Step-by-step explanation:
Gift bag is shaped in a rectangular prism.
<em> rectangular volume: length * width * height</em>
( 2w + 4 ) ( w ) ( 18 - w ) = 1152
( 2w² + 4w ) ( 18 - w ) = 1152
-2w³+32w² +72w = 1152
-2w³+32w² +72w - 1152 = 0
w = 16 , -6 , 6
w = 16 , 6
- length = ( 2w + 4 ) = 36 inch , 16 inch
- width = ( w ) = 16 inch , 6 inch
- height = ( 18 - w ) = 2 inch , 12 inch
