x x h The figure above shows the design of a large water tank in the shape of a cuboid with a square base and no top. The square base is of length x metres and its height is h metres. It is given that the volume of the tank is 500m³. (a) The surface area of the tank is given by A= A = x² + (1000/x) A = x² (2000/x) A = x² + (2000/x) A = x² - (1000/x) (b) Find the value of x for which A is stationary. Put your value of x as a whole number. (c) Find the nature of the Area A at the given point X.
