A right prism has a right triangular bases ABC and A’B’C’ which right angles at A and A’.the edge AA’ is 20 cm long,side AB is 24 cm long ,and side AC is 18 cm long .if a plane is passed through the edge AC,cutting the opposite edge BB’ at a point 14cm from B”. find the distance from point B to this plane .also , Find the area of this plane .



This is actually a truncated prism. there is a proper formula for it
