Joey and Harper are making homemade lemonade by juicing lemons. Joey squeezed 2 1/8 cups of lemon juice and Harper squeezed 1 2/3 cups. How much lemon juice do they have combined?

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 !
