Final answer:
The volume of the box is 8,610 cubic inches, rounded to the correct number of significant figures.
Step-by-step explanation:
The volume of the box can be found by multiplying the three dimensions: 18.4 inches x 17.92 inches x 26 inches = 8,607.1552 cubic inches. Since the given dimensions have different numbers of significant figures, we need to express the volume to the correct number of significant figures.
The least number of significant figures among the given dimensions is 3 (17.92 inches), so we need to round the volume to 3 significant figures. Rounding 8,607.1552 to 3 significant figures gives us the answer: 8,610 cubic inches.
This is the closest option to the correct answer.
