Answer 1

Question -find the length of largest rod that can be placed in a room of 10 m by 8 m by 6 m

Answer. Given length l = 12 m breadth b = 9 m and height h = 8 m Longest rod that can be placed in a room is nothing but its diagonal. Length of diagonal of a cuboid = √(l2 + b2 + h2) Length of longest rod = √(122 + 92 + 82) m = √(144 + 81 + 64) m = √289 m = 17 m Thus the length of the longest rod is 17 m

Answer 2

here is the answer of your question

largest rod is equal to the diagonal of the room.

so diagonal of cuboid =under root a^2 +b^2 +c^2

so, under root 10^2+8^2 +6^2

under root 100+64+36=under root 200=14.4
