ometry — A = i a X nihence, as before — X =\a. {f) Average of x^. Tiievolume of a rectangularblock is found by multiply-ing together the cross-sec-tion and altitude of theblock. In the same waythe volume of other figures may be found by multiplying to-gether the average cross-section and the… … 1102 APPENDIX IX. o a V= x^ X «• Now by geometry — F = ^ a^ X «; hence x^ = h a\ (2) We have already seen that the average of the squares ofnumbers from 0 to 10 is approximately equal to 33^, anilthat when the squares are taken closer and closer together,there is a still closer approach to this…
