The equation for the volume of a rectangular prism is:
V = lwh
where V = volume, l = length of base, w = width of base, and h = height of the prism.
From your picture, you can see that the length, l = 16cm, width, w = 9cm, and the height of the prism, h = 4cm. Plug these numbers into the equation and solve for volume:

--------
Answer: D) 576 cm^3
