Answer:
85.6 square units.
Explanation:
The surface area of a rectangular prism is the sum of the areas of all six faces. To find the surface area of the given rectangular prism, we can use the formula:
Surface Area = 2lw + 2lh + 2wh
where "l" is the length, "w" is the width, and "h" is the height.
Substituting the given values, we get:
Surface Area = 2(6.8)(1.6) + 2(6.8)(3.8) + 2(1.6)(3.8)
= 21.76 + 51.68 + 12.16
= 85.6
the surface area of the rectangular prism is 85.6 square units.
