Answer 1

Step-by-step explanation:-

Seeing logically and diagramitacally, the largest diameter that the hemisphere could have is equal to the lenght of the side of the square.

Area of block=(area of 5 sides of cube)+ar(hemisphere)+ar(partial covered                                              

                           cube side)

                     =5(10)² + 2π(5)² + [10²-π(5)²]

                     =500+157+21.5

                     =678.5cm²

Cost of painting=5×678.5/100

                          =33.925≈34 rupees

I have taken π=3.14
