To calculate the volume of a right rectangular prism, you need to multiply its length by its width by its height. The formula for the volume (V) of a right rectangular prism is given by:
V = length × width × height
Now, given the dimensions of the right rectangular prism as 3 inches (length), 5 inches (width), and 8 inches (height), we can plug these values into the formula:
V = 3 inches × 5 inches × 8 inches
V = 15 inches² × 8 inches
V = 120 inches³
Therefore, the volume of the right rectangular prism is 120 cubic inches. So, the correct answer is:
120in³
