Remember that Area is always in square units (e.g., cm2c m squared ) and Volume is always in cubic units (e.g., cm3c m cubed
Think of an ice cream cone or a party hat. It involves a radius ( ), height ( ), and slant height ( r2+h2the square root of r squared plus h squared end-root Curved Surface Area (CSA): πrlpi r l Total Surface Area (TSA): Volume: A perfectly round 3D object, like a football.
