उत्तर
\[\text { Dimension of the cuboid: } \]
\[ \text { Length = 10 cm } \]
\[Breadth = 12 cm\]
\[\text { Height = 14 cm }\]
\[\text { Surface area of the cuboid = 2 } \times (\text { length } \times \text { breadth + breadth } \times \text { height + length } \times\text { height })\]
\[ = 2 \times (10 \times 12 + 12 \times 14 + 10 \times 14)\]
\[ = 2 \times (120 + 168 + 140)\]
\[ = 856 {cm}^2 \]
