Answer 1

\[\text { Dimension of the cuboid: } \]

\[ \text { Length = 10 cm } \]

\[Breadth = 12 cm\]

\[\text { Height = 14 cm }\]

\[\text { Surface area of the cuboid = 2 } \times (\text { length } \times \text { breadth + breadth } \times \text { height + length } \times\text {  height })\]

\[ = 2 \times (10 \times 12 + 12 \times 14 + 10 \times 14)\]

\[ = 2 \times (120 + 168 + 140)\]

\[ = 856 {cm}^2 \]
