To find the surface area of a right rectangular prism, you can use the formula:
Surface Area = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height.
Given the measurements of length = 4.5 cm, width = 3.5 cm, and height = 2.5 cm, you can substitute these values into the formula:
Surface Area = 2(4.5)(3.5) + 2(4.5)(2.5) + 2(3.5)(2.5)
Surface Area = 31.5 + 22.5 + 17.5
Surface Area = 71.5 cm²
Therefore, the correct answer is 71.5 cm².
Surface Area = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height.
Given the measurements of length = 4.5 cm, width = 3.5 cm, and height = 2.5 cm, you can substitute these values into the formula:
Surface Area = 2(4.5)(3.5) + 2(4.5)(2.5) + 2(3.5)(2.5)
Surface Area = 31.5 + 22.5 + 17.5
Surface Area = 71.5 cm²
Therefore, the correct answer is 71.5 cm².
