Question

what can be longest rod that can fit in Room of 825cm×675cm×450cm

Answer 1

Given :
Length = 825 cm
Breadth = 675 cm
Height = 450 cm
Length of the longest rod that can be placed =
$\sqrt{ {l}^{2} + {b}^{2} + {h}^{2} }$
$\sqrt{ {825}^{2} + {675}^{2} + {450}^{2} }$
$\sqrt{680625 + 455625 + 202500}$
$\sqrt{1338750}$
= 1157.04 cm
