find the volume and the lateral area of a concrete column in the form of a right prism whose base is a regular hexagon of side 50 cm. and whose altitude is 10 m.

Sagot :

vol = area of base x height
area of regular hexagon side 50cm is given by the formula      ( na²√3)/4  where  n = # sides, a = length of side
thus     Vol  =    (6* 50²√3)/4*10cm
           =  1299cc
Area of lateral surfaces
         =  6*50*10            /  6 surfaces
         = 3000sqcm
