Hey guys i don't know how to work out these questions:

1.  A square sheet of cardboard has edges of length 20 cm. Four equal squares of edge length x cm are cut out of the corners and the sides are turned up to form an open rectangular box.

b)Find the volume, V cm3, of the box in terms of x.
c Find the volume of the box when x = 5.
d Find the values of x for which the volume is 500 cm3.
