you have 240 cubic inches of clay with which to make a sculpture shaped as a rectangular prism. You want the width to be 4 inche
SpyIntel [72]
Length=6, width=2, height=20. We can write a function to solve this problem. Suppose the length of the sculpture is x inches. Then the width is (x-4) inches, and the height (3x+2) inches. Their product is the volume of the clay: x*(x-4)*(3x+2)=240. Solve the equation, the only real answer is 6, so the length is 6 inches. Width is 6-4=2, and height is 3*6+2=20.

3*10^(-6 - - 8)

3*10^(-  6 + 8)

3^10^2 or 300 times larger
