Question

the surface area of cuboid = 252 square cm.It lenght and breadth are 8cm ,7cm respectively. Find height ​

Answer 1

Answer: height = 4.66cm

Step-by-step explanation: let the height be = x

TSA of cuboid = 2(lb+bh+hl)

                252  =2(56+7x+8x)

                252 = 2(56+15x)

                252/2=56+15x

               126-56 = 15x

               70 = 15x

                70/15 = x

                 x = 4.66
