Final answer:
To calculate the surface area of a rectangular prism, use the formula 2(length * width + width * height + height * length). Substituting the given dimensions, the surface area is 122 square inches.
Step-by-step explanation:
To calculate the surface area of a rectangular prism with dimensions of 4 inches, 3 inches, and 7 inches, you can use the formula: 2(length * width + width * height + height * length). Substituting the given dimensions into the formula, we get: 2(4*3 + 3*7 + 7*4) = 2(12 + 21 + 28) = 2(61) = 122 square inches.
