Question

Find the total surface area of the cuboid whose dimensions are as follows (i)l=14cm. B=9cm,. H=10cm

Answer 1

Total Surface Area = 2(lb +bh + lh)

                               = 2 [(14*9)+(9*10)+(14*10)]

                               = 2(126+90+140)

                               = 2(356)

                               = $712 cm^{2}$

Answer 2

Answer =712cm ^2.
