Final answer:
The volume of a rectangular prism with the given dimensions is calculated using the formula Volume = Length x Width x Height, resulting in 1 inch cubed.
Step-by-step explanation:
The student asks to find the volume of a rectangular prism that has a length of 2 inches, a width of 1 inch, and a height of one-half inch. To find the volume, we use the formula for the volume of a rectangular prism, which is:
Volume = Length × Width × Height
By substituting the given dimensions into the formula, we get:
Volume = 2 inches × 1 inch × 0.5 inch
Volume = 1 inch cubed (in³)
Therefore, the correct answer is B. 1 inch cubed.
