Hey mate ,

The longest rod which can come into a cuboid is it's diagonal ,

Formulae of diagonal of cuboid

 =  \sqrt{ {l}^{2}  +  {b}^{2} +  {h}^{2}  }

where , l = length = 825 cm = 8.25 m

b = breadth = 675 cm = 6.75 m

h = height = 450cm = 4.5 m

Thus ,

 =  \sqrt{ {(8.25)}^{2}  + ( {6.75}^{2}) + ( {4.5}^{2})  }

 =  \sqrt{68.0625 + 45.5625 + 20.25}

 =  \sqrt{133.875}

 = 11.57 \: m(approx)

HOPE YOU FIND IT HELPFUL !

DO MARK IT AS BRAINLIEST !!

Answer:

plz take the length of diagonal as

Step-by-step explanation:

as diagonal = square root of sum of square of sides see (diagonal)^2 = a^2 + b^2 + c^2

and diagonal^2 = 825)^2 + (675)^2 + (450)^2

therefore length of longest rod is == ( 6,80,625 + 4,55,625 + 202500 )^(1/2)

= (1338750)^(1/2)

= 1157 cm (approx)
