Yogita Ingle 6 years, 3 months ago

According to the question,

Diameter of hemisphere = Edge of cube
= l

Radius of hemisphere =

Curved Surface Area of hemisphere = 2 π r²
Surface Area of cube = 6(Edge)2

Total surface area of solid = Surface area of cubical part + CSA of hemispherical part - Area of base of hemispherical part

= 6 (Edge)² + 2πr² – πr²

= 6 (Edge)² + πr²

TSA of Solid = 6l² + π x ()²
