Question

hi

plz answer it fast​

Answer 1

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 !

Answer 2

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)
