Given: length (l) =1.5 m, breadth (b) = 1 m and height (h) =5 m

Surface area of the brick= 2{(1.5 × 1) + (1 × 5) + (1.5 × 5)} m2

                                                    = 28 m2

Edge of sheet  =1 m

Area of 1 sheet= 1 m2

Let “N” numbers of square sheets of side 1 m are required to cover the almirah.

Thus, N×1 m2=28 m2
