Answer:
Length ( l ) = 8m 50cm = 8.5m
Breadth ( b ) = 6m 25 cm = 6.25m
Height ( h ) = 4m 75cm = 4.75m
Note :The maximum length of the rod that can be placed in a cuboid is along the diagonal. So, the rod of length equal to the diagonal is the maximum length which can be placed in cuboid.
Longest Rod =√l^2 + b^2 +h^2)
= √ (8.5)^2 + ( 6.25) ^2 + (4.75)^2
=√72.25+39.0625+22.5625
=√133.875
=11.57043625
