Answer 1

To find the surface area of a right rectangular prism, we need to use the formula:

Surface Area = 2lw + 2lh + 2wh

Given the measurements:
length = 4.5 cm
width = 3.5 cm
height = 2.5 cm

Substituting these values into the formula, we have:

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

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