CUBOID Let length = l, breadth = b and height = h units. Then i.Volume = (l x b x h) cubic units. ii.Surface area = 2(lb + bh + lh) sq. units. iii.Diagonal = l2 + b2 + h2 units. 2.CUBE Let each edge of a cube be of length a. Then, i.Volume = a3 cubic units. ii.Surface area = 6a2 sq. units. iii.Diagonal = 3a units. 3.CYLINDER Let radius of base = r and Height (or length) = h. Then, i.Volume = (r2h) cubic units. ii.Curved surface area = (2rh) sq. units. iii.Total surface area = 2r(h + r) sq. units. 4.CONE Let radius of base = r and Height = h. Then, i.Slant height, l = h2 + r2 units. ii.Volume = r2h cubic units. iii.Curved surface area = (rl) sq. units. iv.Total surface area = (rl + r2) sq. units. 5.SPHERE Let the radius of the sphere be r. Then, i.Volume = r3 cubic units. ii.Surface area = (4r2) sq. units. 6.HEMISPHERE Let the radius of a hemisphere be r. Then, i.Volume = r3 cubic units. ii.Curved surface area = (2r2) sq. units. iii.Total surface area = (3r2) sq. units. Note: 1 litre = 1000 cm3. Some where under roots are missing plz check that, sorry for your inconvenience,
