Dear student,... • L.S.A = Lateral surface area • T.S.A = Total surface area. to identify whether the question is asking to find L.S.A or T.S.A :- • L.S.A is the area of all regions except the base • T.S.A is the total area of the solid figure. => Type of questions for L.S.A •Question may come like excluding the base. • Flower vase. ( in dat case, L.S.A + area of plane fig.) • Area of Walls => Type of questions in T.S.A • Find the total surface area • find the area of the room as u know csa means curved surface area so it is used when we need to find the area of a figure without the base or the roof and we find the tsa when we need to find the area of a figure adding the base and the roof.... regards
