203 = 8000 Let f(x) = 8132 - x3 then f'(x) = the derivative of f(x) = -3x2 Using Newton-Raphson method, a better estimate is 20 - f(x)/f'(x) = 20 - 132/(-3*202) = 20 + 132/1200 = 20 + 11/100 = 20.11
2 cube root 6
If you know the volume of the cube, then you just cube root the volume e.g. Vol(cube) = 1000 cm^(3) Side length = [1000 cm^(3)] ^(1/3) = 10 cm Note the change in units from 'cm^(3) ' to 'cm'. Because you are changing a volume to a length. The index number of '1/3' means the 'cube root'.
