उत्तर
\[\text { Dimensions of the cuboid: }\]
\[\text { Length = 2 m }\]
\[\text { Breadth = 4 m }\]
\[\text { Height = 5 m } \]
\[\text { Surface area of the cuboid = 2 } \times (\text { length } \times \text { breadth + breadth } \times\text { height + length }\times \text { height })\]
\[ = 2 \times (2 \times 4 + 4 \times 5 + 2 \times 5)\]
\[ = 2 \times (8 + 20 + 10)\]
\[ = 76 m^2 \]
