Answer:
the surface area of the solid is 76m²
Explanation:
Based on the information you provided, it seems like you are asking about the surface area of a rectangular prism with dimensions 2m x 4m x 5m. The surface area of a rectangular prism can be calculated using the formula:
Surface Area = 2lw + 2lh + 2wh
where l, w, and h represent the length, width, and height of the prism, respectively.
Substituting the given dimensions into the formula, we get:
Surface Area = 2(2m)(4m) + 2(2m)(5m) + 2(4m)(5m) = 16m² + 20m² + 40m² = 76m²
Therefore, the surface area of the solid is 76m².
