First, we can find the surface area of the right rectangular prism by using the formula:
Surface Area = 2lw + 2lh + 2wh
Plugging in the given dimensions:
Surface Area = 2(2)(3) + 2(2)(8) + 2(3)(8)
Surface Area = 12 + 32 + 48
Surface Area = 72 square feet
Therefore, the surface area of the right rectangular prism is 72 square feet.
Correct response: 72 square feet
Use the image to answer the question.
An illustration shows a right rectangular prism with a length of 2 feet, height of 8 feet, and width of 3 feet. The edges that are obscured are represented by dashed lines.
Justify the formula, and find the surface area of the right rectangular prism using nets or decomposition.
