Answer:

Edge of cube = 5 cm

Total surface area of cube = 6a^2

where a is the side

So, the total surface area of given cube = 6(5)^2

                                                                  = 150 cm^2

Lateral surface area of cube = 4a^2

where a is the side

So, Lateral surface area of given cube = 4(5)^2

                                                                  = 100 cm^2

Now we are supposed to find the surface area of cube open from the top which edge length 30 cm

So, surface Area with one base =5(a)^2

where a is the side

So, the surface area of given cube =5(30)^2

                                                          =4500 cm^2
