Question

13. The length, breadth and height of a room are 8 m,
25 m 75 cm and 4 m 50 cm, respectively. Find the
largest rod that can measure the three dimension
of the room exactly.​

Answer 1

Step-by-step explanation:

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

$= \sqrt{8 {}^{2} + {(25.75)}^{2} + {(4.5)}^{2} }$

$= \sqrt{64 + 663.0625 + 20.25}$

$= \sqrt{747.3125}$

$= 27.33m \: (approx)$
