Single Metal Edge

Single Metal Edge

three blocks of metal whose edges r 3,4,5 judged, cast and formed in the area of single cube.surface new cube?

three cubes of metal, whose edges are 3,4,5 cms.respectively, melts and forms in a single cube watage.then hub surface again?

First, it is a matter of Math. Second, are cubes therfore all lengths of the edges are the same as each other. ie, the first has edges that are all 3 long. etc. The volume of a cube is the "hub" of the length of an edge – which is the length of the long length is thus the volume of the large cube is 3x3x3 + 4x4x4 + 5x5x5 = 216. Now work backwards and find the "square root" of 216 – which is the number multiplied by itself twice to make 216. (= 6) The surface of a cube consists of six identical squares whose edge length is now known (6). The area of a square is the edge length of time itself – 6×6 = 36. Multiply this by 6 and you have your answer! (216) Note, this answer is just the same as the volume when the length = 6. (This only works if the same type of metal in all cubes – But one can assume that is why this issue.)
