Answer 1

★ Question

find the length of the longest pole that can be placed in a room of dimension 10m×10m×5m .

★ Answer

↪concept :

The longest pole that can be put in the cuboid will be the the longest diagonal of a cuboid.

diagonal of cuboid

$= \sqrt{l {}^{2} + h {}^{2} + b {}^{2} }$

the longest pole that can be placed in room

= diagonal of room

$= \sqrt{10 {}^{2} + 10 {}^{2} + 5 {}^{2} }$

$= \sqrt{100 + 100 + 25}$

$= \sqrt{225}$

$= 15 \: m$

therefore ;the length of the longest pole that can be placed in a room of dimension 10m×10m×5m

is 15 m.
