The surface area of a right rectangular prism is calculated by finding the sum of the areas of all six faces.
The area of each face can be found by multiplying the length and width of each respective face.
Face 1: w * l = 12 in. * 18 in. = 216 in² (area of the bottom face)
Face 2: w * l = 12 in. * 18 in. = 216 in² (area of the top face)
Face 3: w * h = 12 in. * 8 in. = 96 in² (area of one side face)
Face 4: w * h = 12 in. * 8 in. = 96 in² (area of the opposite side face)
Face 5: l * h = 18 in. * 8 in. = 144 in² (area of one end face)
Face 6: l * h = 18 in. * 8 in. = 144 in² (area of the opposite end face)
Adding up all the areas of the six faces:
216 in² + 216 in² + 96 in² + 96 in² + 144 in² + 144 in² = 912 in²
The surface area of the right rectangular prism is 912 in².
