Question

find the surface area of cuboid whose length is 5 1/2 cm , breadth is 4 cm , height is 10 1/2 cm​

Answer 1

Answer:

232 cm

Step-by-step explanation:

⇒  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)

                                                     =232cm

∴  Total surface area of cuboid =232cm
