Edurne hace cada día en su pastelería, de lunes a sábado, 500ga-lletas. Si ella todos los días come 4 y regala 40, ¿Cuántas puede vender?

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 !
