A fixed number of cuts will result in fixed number of pieces 0 votes 0 votes Nawed Shaikh commented Sep 7, 2018 i edited by Nawed Shaikh Sep 7, 2018 reply Follow Share Is the answer 15? 0 votes 0 votes Please log in or register to add a comment.
Best answer 2 votes 2 votes Minimum cubelets can be only achieved when we cut the cuboid from each dimensions( 3 dimension). for minimum division we factorise 192 = 4*8*6 (we need n-1 cuts to divide into n pieces) therefore total cuts = 3 +7+5 = 15 answer. arvin answered Sep 7, 2018 • selected Sep 8, 2018 by hrcule arvin comment Share Follow See all 0 reply Please log in or register to add a comment.
1 votes 1 votes The general Solution to such problem is to find three factors of x ( a , b and c ) where a*b*c = x ( here it is 192) such that a,b, and c are closest possible to CubeRoot(x). Then minimum number of Cuts would be (a-1) + (b-1) + (c-1). Nawed Shaikh answered Sep 7, 2018 Nawed Shaikh comment Share Follow See all 0 reply Please log in or register to add a comment.
