Question

find t total surface area lateral surface area and the length of the diagonal of a cube whose edge is 12dm​

Answer 1

Answer:

i think you mean cm but even if it isnt just change cm into dm

Total surface area = 6l^2

                               = 6 * 144

                                = 864 cm2

lateral surface area =4l^2

                                 = 4 * 144

                                  = 576 cm2

diagonal = √3 * l

              = √3  * 12

               = 20.784
