Final answer:
The area of one face of the rectangular prism is 36 square inches.
Step-by-step explanation:
The area of one face of a rectangular prism can be calculated by multiplying the length and width of the face. In this case, the dimensions of the rectangular prism are given as 4 inches, 9 inches, and 7 inches. To find the area of one face, we can use the formula: Area = length x width. Therefore, the area of one face of the rectangular prism is 4 inches x 9 inches = 36 square inches.
