Question

Find the Total surface area of a cuboid when length is 10cm and breadth is 35cm and heights is 1.2m

Answer 1

length of cuboid = 10 cm

breadth = 35 cm

height = 120 cm

total surface of cuboid = 2 (lb + bh + hl)

                                      = 2 ( 10×35 + 35×120 + 120×10)

                                      = 2 ( 350 + 4200 + 1200)

                                      = 2( 5750)

                                      = 11500 cm²
