Use the formula for the surface area of a rectangular prism to find the surface area of a shape with the following measurements length 4.5 cm with 3.5 cm and height 2.5 cm
The formula for the surface area of a rectangular prism is:
Surface Area = 2(length × width + length × height + width × height)
Given:
Length = 4.5 cm
Width = 3.5 cm
Height = 2.5 cm
Substituting the given values into the formula:
Surface Area = 2(4.5 cm × 3.5 cm + 4.5 cm × 2.5 cm + 3.5 cm × 2.5 cm)
Calculating the expression inside the brackets:
Surface Area = 2(15.75 cm² + 11.25 cm² + 8.75 cm²)
Calculating the values inside the brackets:
Surface Area = 2(35.75 cm²)
Multiplying by 2:
Surface Area = 71.5 cm²
Therefore, the surface area of the rectangular prism is 71.5 cm².
