Answer 1

yeah


the correct answer is a option

Answer 2

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 =$5(30)^2$

                                                          =$4500 cm^2$
