The formula for the surface area of a right rectangular prism is given by 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Plugging in the given measurements, we have:
2(4.5 cm)(3.5 cm) + 2(4.5 cm)(2.5 cm) + 2(3.5 cm)(2.5 cm)
Simplifying this expression, we have:
31.5 cm² + 22.5 cm² + 17.5 cm² = 71.5 cm²
Therefore, the surface area of the shape is 71.5 cm².
