Question

A cuboid dimension 10 centimetre by 2 cm by 2 cm is divided into 5 cube of edge 2 cm find the ratio of the total surface area of the cuboid and that of the cube

Answer 1

Answer:

Step-by-step explanation:

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

                        = 2(20 + 4 + 20)

                        = 2 x 44

                        = 88cm^2

TSA of cube = 6a^2

                     = 6 x 2 x 2

                     = 24cm^2

TSA of cuboid : TSA of cube = 88 : 24

                                                = 22 : 6

                                                = 11 : 3
