The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?

A=bxh3.2x1.8=5.76 centimeters square

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 !
