Cuboid
Mensuration of Class 10
Total surface Area (T.S.A.): The area of surface from which cuboid is formed. There are six faces (rectangular), eight vertices and twelve edges in a cuboid.
(i) Total surface Area (T.S.A.) = 2 [l × b + b × h + h × l]
(ii) Lateral Surface Area (L.S.A) = 2 [b × h + h × l]
(or Area of 4 walls) = 2h [l + b]
(iii) Volume of Cuboid = (Area of base) × height
= (l × b) × h
(iv) Length of diagonal = √12 + b2 + h2
