Find the total surface area of. the solid. Sol. \u2013 Total surface area of cube = 6 5 5. = 150 cm\u00b2. The surface area of block = Total surface area of block + curved surface area of the hemisphere \u2013 area of the base of the hemisphere. = \u03c0r\u00b2 + 2\u03c0r\u00b2 = (150 +\u03c0r\u00b2) cm\u00b2. = 150 cm\u00b2 + [ 22/7   4.2/2  4.2/2] cm\u00b2. =( ) cm\u00b2 = cm\u00b2.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
