The formula for the surface area of a right rectangular prism is 2lw + 2lh + 2wh.

Using the given measurements:
Length = 4.5 cm
Width = 3.5 cm
Height = 2.5 cm

Substituting these values into the formula:
2(4.5 cm)(3.5 cm) + 2(4.5 cm)(2.5 cm) + 2(3.5 cm)(2.5 cm)

= 31.5 cm2 + 22.5 cm2 + 17.5 cm2

= 71.5 cm2

Therefore, the surface area of the shape is 71.5 cm2.

The formula for the surface area of a right rectangular prism is 2lw + 2lh + 2wh.

Since all edge lengths of the prism measure 12.75 cm, we can substitute this value into the formula:

2(12.75 cm)(12.75 cm) + 2(12.75 cm)(12.75 cm) + 2(12.75 cm)(12.75 cm)

= 326.25 cm2 + 326.25 cm2 + 326.25 cm2

= 978.75 cm2

Therefore, the surface area of the shape is 978.75 cm2.
