Use the formula for the surface area of a right rectangular prism to find the surface area of a shape with the following measurements: length = 4.5 cm, width = 3.5 cm, and height = 2.5 cm.(1 point) Responses 35.75 cm2 35.75 cm squared 10.5 cm2 10.5 cm squared 63 cm2 63 cm squared 71.5 cm2
The formula for the surface area of a right rectangular prism is 2lw + 2lh + 2wh.
In this case,
l = 4.5 cm
w = 3.5 cm
h = 2.5 cm
Substituting these values into the formula, we get:
2(4.5)(3.5) + 2(4.5)(2.5) + 2(3.5)(2.5)
Simplifying, we get:
63 + 22.5 + 17.5
Adding these values together, we get:
103
Therefore, the surface area of the shape is 103 cm².
