Pyramid has height h and a square base with side x. The volume of such a pyramid is given by V=1/3x^2h. Erosion causes the height to decrease at a rate of 0.006 m/year, and the sides to decrease at a rate of 0.004 m/yr, when x=180m h=150m . Estimate at this moment in time, how fast the volume of the pyramid is changing
