Question

find the length of the largest pole that can be placed in hall 10m long 10m wide and 5 m high

Answer 1

Hi ,

Dimensions of the hall are,

Length = l = 10m

Breadth = b = 10 m

Height = h = 5 m

Length of the largest pole =

√ ( l² + b² + h² )

= √ ( 10² + 10² + 5² )

= √ ( 100 + 100 + 25 )

= √ 225

= √ 15²

= 15 m

I hope this helps you.

Answer 2

Hey!

Dimensions of the rectangular hall:
Length (l) = 10 m
Breadth (b) = 10 m
Height (h) = 5 m

Length of the largest pole = diagonal of rect. hall

= √( l²+b²+h²)
= √(10²+10²+5²)
= √( 100+100+25)
= √225
= 15 m
