To find the surface area of a rectangular prism, we can use the formula:
S = 2lw + 2wh + 2lh
Given that the length, width, and height of the rectangular prism are:
Length (l) = 2 cm
Width (w) = 3 cm
Height (h) = 4 cm
Plugging the values into the formula, we have:
S = 2(2)(3) + 2(3)(4) + 2(2)(4)
S = 12 + 24 + 16
S = 52 cm²
Therefore, the surface area of the rectangular prism is 52 cm².
Therefore, the correct answer is option C. S = 52 cm².
