Question

Find the surface area of a cuboid whose llength = 2 m, breadth = 4 m, height = 5 m .

Answer 1

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

\[\text { Length = 2 m  }\]

\[\text { Breadth = 4 m  }\]

\[\text { Height = 5 m } \]

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

\[ = 2 \times (2 \times 4 + 4 \times 5 + 2 \times 5)\]

\[ = 2 \times (8 + 20 + 10)\]

\[ = 76 m^2 \]
