Final answer:
To find the area of the base of a right rectangular prism with a volume of 30 cubic inches and height of 6 inches, you divide the volume by the height, resulting in an area of 5 square inches.
Step-by-step explanation:
The question asks to find the area of the base of a right rectangular prism with a known volume and height. The formula to calculate the volume of the prism is V = length × width × height, and we know the volume (V) is 30 cubic inches, and the height (h) is 6 inches.
To find the base area (A), we rearrange this formula to A = V/h, which gives us A = 30/6. Therefore, the base area is 5 square inches. So, the correct answer is a. 5 sq. inches.
