Use the formula for the surface area of a right rectangle prism to find the surface area of a shape with the following measurements: length=4.5cm, width=3.5cm, and height=2.5cm
The formula for the surface area (SA) of a right rectangular prism is:
SA = 2lw + 2lh + 2wh
Given:
length (l) = 4.5 cm
width (w) = 3.5 cm
height (h) = 2.5 cm
Substituting the values into the formula, we get:
SA = 2(4.5)(3.5) + 2(4.5)(2.5) + 2(3.5)(2.5)
Simplifying the expression, we get:
SA = 31.5 + 22.5 + 17.5
Adding the numbers together, we find the surface area:
SA = 71.5 cm²
Therefore, the surface area of the given shape is 71.5 square centimeters.
