The equation that represents the volume of the storage container(rectangular prism) in terms of its width is 12w + 6w²
volume of a rectangular prism = lwh
where
Therefore,
h = 6 ft
l = 2 + w
Hence,
volume of the rectangular prism = (2 + w) × w × 6
volume of the rectangular prism = (2w + w²)6
volume of the rectangular prism = 12w + 6w²
