Arailway system on a hillside moves passengers at a constant rate to an elevation of 50 m. the elevations of a train are given for 2 diffrent locations

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !

Elaborate for this question.
