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=4.5cm, width=3.5cm, and height=2.5cm.
The formula for the surface area of a right rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Where:
l = length
w = width
h = height
Substituting the given measurements:
Surface Area = 2(4.5cm)(3.5cm) + 2(4.5cm)(2.5cm) + 2(3.5cm)(2.5cm)
Simplifying the equation:
Surface Area = 31.5cm² + 22.5cm² + 17.5cm²
Calculating the sum:
Surface Area = 71.5cm²
Therefore, the surface area of the shape is 71.5 square centimeters.
