    1. Best Answer

      Here,
      Length of cabinet (l) = 2 m,
      Breadth of cabinet (b) = 1 m
      And Height of cabinet (h) = 1.5 m
      ∴ Surface area of cabinet = lb+2(bh+hl)
      = 2 x 1 + 2 (1 x 1.5 + 1.5 x 2)
      = 2 + 2 (1.5 + 3.0) = 2 + 9.0 = 11 m2
      Hence, the required surface area of cabinet is 11 m².
