Answer 2

Length of a cuboid (l)=8cm

⇒  Breadth of a cuboid (b)=7cm

⇒  Height of a cuboid (h)=4cm

⇒  Total surface area of cuboid =2(lb+bh+hl)          

                                                      =2(8×7+7×4+4×8)

                                                      =2(56+28+32)

                                                      =2(116)

                                                      =232cm2

Total surface area of cuboid =232cm2
