If a store room of a house is in the shape of a cuboid having a length of 3m, a width of 2m, and a height of 4m, find the total area of its four walls. |
50 m2 20 m2 40 m2 24 m2 |
40 m2 |
We know that, Area of 4 walls = 2(l + b)h Length = 3 m, width = 2 m, height = 4 m. Area of walls = 2(3 + 2)4 = 40 |
