Question

if the length of the longest rod that can be placed in a room of dimension 20 m× 20 m×10 m​

Answer 1

Step-by-step explanation: the longest rod will theoretically be the diagonal of  cuboid

so

  diagonal of base =√ 20²+20²

                               =√800

(diagonal of base)²+h²=(diagonal of room)²

(√800)²+10²=(diagonal of room)²

800+100=(diagonal of room)²

900=(diagonal of room)²

30 m =diagonal of room
