the length of the longest rod that van kept Kept in the room is.....diagonal of cuboid..
Step-by-step explanation:
- diagonal of cuboid = square root( l² + b² + h²)
= square root ( 20² + 20² +10²)
= square root ( 400 + 400 +100 )
= root (900)

Answer:
800 meters
Step-by-step explanation:
when you place the rod diagonally on the floor with dimensions 20 x 20 it becomes the hypotenuse and using pythagoras you can find its length.
hypotenuse^2 = side^2 + side^2
= 20^2 + 20^2
= 400 + 400
= 800m
