The surface area of a rectangular prism can be calculated using the formula 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
In this case, the dimensions are 3 dm × 4 dm × 5 dm.
So, the surface area would be:
2(3)(4) + 2(3)(5) + 2(4)(5)
= 24 + 30 + 40
= 94 dm^2
Therefore, the surface area of the rectangular prism is 94 square decimeters.
