Step-by-step explanation:
To calculate the volume of the interior of a rectangular box, you can use the formula Volume = length × width × height. Given the dimensions of 5 inches by 4 inches by 3 inches, we can find the volume by multiplying these dimensions together:
- Volume = 5 in. × 4 in. × 3 in.
- Volume = 20 in. × 3 in.
- Volume = 60 cubic inches.
Therefore, the volume of the interior of the box is 60 cubic inches, which corresponds to option A).
