What is the surface area formula for a trapezoidal prism?

Surface Area of a Trapezoidal Prism = ##a(l + h) + b(l + h) + lc + ld##
Surface Area of a Trapezoidal Prism = ##a(l + h) + b(l + h) + lc + ld##
Where
##a b c d## are sides of the trapezium.
##h ##= Altitude and ## l ##= Height of the prism.
