Question

each edge of a cube is 18 cm long find the total surface area and lateral surface area of a cube​

Answer 1

Answer:

side=18cm

TSA=6a^{2}

LSA= 4a^{2}

therefore

TSA=6×18×18=1944 square cm

LSA=4×18×8=square cm

Step-by-step explanation:

Answer 2

Answer:

Side of cube = 18 cm

Total surface area of cube = 6a²

                                              =6×18×18

                                              =1944 cm²

Lateral surface area of cube = 4a²

                        =4×18×18

                           =1296
