Question

the length of a longest pole that can be put in a room of dimension of 10 metre into 10 into 5​

Answer 1

Step-by-step explanation:

the length of a longest pole that can be put in a room of dimension

Answer 2

Given :-

• Length of Room = 10m
• Breadth of Room = 10m
• Height of Room = 5m

To Find :-

• The Maximum length of the pole which can be placed in a room

Solution :-

❏ Maximum length of the Pole means the Length of the Diagonal of the Room.

⟹⠀⠀ Diagonal = √(L)² + (B)² + (H)²

⟹⠀⠀ Diagonal = √(10)² + (10)² + (5)²

⟹⠀⠀ Diagonal = √100 + 100 + 25

⟹⠀⠀ Diagonal = √200 + 25

⟹⠀⠀ Diagonal = √225

⟹⠀⠀ Diagonal = 15m

Thus, Maximum length of the Pole which can be placed in the room is 15m

Tips and Tricks :

• The Diagonal of a cuboid with dimensions l × b × h is √(L)² + (B)² + (H)².
• The Diagonal of a cube of side a is given by √3 × a.
