Question 1058833
volume of a cube of 10 cm persides is equal to 10^2 = 1000 cubic cm.


volume of a sphere with radius = 10/2 = 5 would be 4/3 * pi * 5^3 = 523.5987756 cubic cm.


amount of wood wasted would be 10 - 523.5987756 = 476.4012244 cubic cm.


percent of wood wasted would be 476.4012244 / 1000 * 100 = 47.64012244 percent.


round as required.
