Final answer:
The volume of a juice box with the given dimensions (2 inches by 1 inch by 4 inches) is calculated as 8 cubic inches; hence, the correct answer is option C.
Step-by-step explanation:
To determine the volume of a juice box with dimensions 2 inches in length, 1 inch in width, and 4 inches in height, apply the formula for a rectangular prism: Volume = length × width × height. Substituting the given values, the calculation is 2 inches × 1 inch × 4 inches, resulting in a volume of 8 cubic inches.
Therefore, the accurate selection for the juice box's volume is option C, specifically 8 cubic inches. This straightforward application of the volume formula illustrates the three-dimensional space occupied by the juice box and allows for a precise measurement of its internal capacity.
