Answer:
6√3
Step-by-step explanation:
V = 648•(3½) = 8•81•(3½) where the SQUARE ROOT OF 3 has been written with a fractional exponent V = s3
so s = cube root of this V.
Cube root of 8 is 2; cube root of 81 is 3•3^(1/3) and cube root of square root of 3 is 3^(1/6).
Therefore s = 2•3•3^(1/3 + 1/6) = 2•3•3½ = 6√3.
You will need to get s2 = 36•3 = 108. Finally, T.S.A. = 6 s2 = 6(108) = 648.
210/20=10.5 per hour
So
2000/10.5=190 hours
