We must calculate the lateral area which is given by:
 A = (1/2) * pb * Ap
 Where,
 pb: perimeter of the base
 Ap: Apotema
 Calculating the apothem we have:
 Ap = root ((646/2) ^ 2 + (350) ^ 2)
 Ap = 476.27 feet
 Calculating the perimeter of the base we have:
 pb = 4 * (646)
 pb = 2584 feet
 Substituting values:
 A = (1/2) * pb * Ap
 A = (1/2) * (2584) * (476.27)
 A = 615340.84 m ^ 2
 Answer:
 The minimum amount of glass used for the exterior is:
 A = 615340.84 m ^ 2
