Final answer:
The volume of Sarah's rectangular box is 4900 cubic inches, calculated by multiplying the length (24.5 inches), width (16 inches), and height (12.5 inches) of the box.
Step-by-step explanation:
To calculate the volume of Sarah's rectangular box, which is used to store her markers, we can use the formula for the volume of a rectangular prism: Volume = length × width × height. Given the dimensions of the box are 24.5 inches by 16 inches by 12.5 inches, the calculation would be:
Volume = 24.5 in × 16 in × 12.5 in
Volume = 4900 cubic inches.
So, the volume of Sarah's box is 4900 cubic inches. This allows Sarah to know how much space she has inside the box for her markers.
