To find the surface area of a right rectangular prism, you need to calculate the area of each face and then add them together.
The formula for the surface area of a right rectangular prism is:
Surface area = 2lw + 2lh + 2wh
Given:
Length (l) = 4.5 cm
Width (w) = 3.5 cm
Height (h) = 2.5 cm
Now, plug in the 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 surface area of the shape with the given measurements is 71.5 cm².
