To find the surface area of a right rectangular prism, we use the formula:
Surface Area = 2(length × width + length × height + width × height)
Given measurements:
Length = 4.5 cm,
Width = 3.5 cm,
Height = 2.5 cm
Substituting these values into the formula:
Surface Area = 2(4.5 × 3.5 + 4.5 × 2.5 + 3.5 × 2.5)
= 2(15.75 + 11.25 + 8.75)
= 2(35.75)
= 71.5 cm²
Therefore, the surface area of the given shape is 71.5 cm².
