Question

the edge of 3 cube is 1m 6m 8m they are melted and form a single cube find the edge of new cube ​

Answer 1

Answer:

volume of first cube + volume of second cube  + volume of third cube =        ( 1 )∧3 + ( 6 )∧3 + ( 8 )∧3

1×1×1 + 6×6×6 + 8×8×8

1 + 216 + 512

729 meter cube

since, volume of all three cubes = volume of new cube

∴     729m∧3 = edge∧3

      ( 9 )∧3 = edge∧3

hence,    edge of new cube = 9m.
