An 8 m long cuboidal beam of wood when sliced produces four thousand 1 cm cubes and there is no wastage of wood in this process. If one edge of the beam is 0.5 m, find the third edge.
Length of cuboidal beam = 8 m
One edge of beam = 0.5 m
Let third edge of beam = h m
No. of cubes of side 1 cm (.01 m) produced = 4000
Length of third edge = 0.001 m
