Answer

Final Answer: The surface area of the object is $\boxed{55.6}$ square centimeters.

Steps

Step 1 ：Given a rectangular prism with length (l) = 6.2 cm, width (w) = 1 cm, and height (h) = 3 cm.

Step 2 ：The surface area of a rectangular prism can be calculated using the formula: $2lw + 2lh + 2wh$.

Step 3 ：Substitute the given values into the formula: $2(6.2)(1) + 2(6.2)(3) + 2(1)(3)$.

Step 4 ：Simplify the expression to get the surface area: $55.6$ square centimeters.

Step 5 ：Final Answer: The surface area of the object is $\boxed{55.6}$ square centimeters.
