Answer 1

The formula for the surface area of a right rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

Plugging in the measurements:
Length (l) = 4.5 cm
Width (w) = 3.5 cm
Height (h) = 2.5 cm

Surface Area = 2(4.5)(3.5) + 2(4.5)(2.5) + 2(3.5)(2.5)
Surface Area = 2(15.75) + 2(11.25) + 2(8.75)
Surface Area = 31.5 + 22.5 + 17.5
Surface Area = 71.5 cm^2

Therefore, the surface area of the shape is 71.5 square centimeters.
