Formula of the area of four walls,
=> (area of the base ) + (area of ceiling)
=> Area of base = l * b
=> Area of ceiling = l * b
So,
=> (area of the base ) + (area of ceiling) = 2(l*b)
=> As per Surface area of a cuboid we have 2(l+b)*h
Then finally we get,
Area of four walls = 2(l+b)*h
=> (area of the base ) + (area of ceiling)
=> Area of base = l * b
=> Area of ceiling = l * b
So,
=> (area of the base ) + (area of ceiling) = 2(l*b)
=> As per Surface area of a cuboid we have 2(l+b)*h
Then finally we get,
Area of four walls = 2(l+b)*h
formula of four Wall=1 \2×base ×height
area of celling =length×breadth
The walls are not triangular
2(l+b)h
l*b
