Answer:

The length of the longest rod that can be placed in a room is it's diagonal.

Now, the Length of diagonal of a cuboid = √(l2 + b2 + h2)

So, Length of longest rod = √(144 + 81 + 64) m

√(144 + 81 + 64) m = √289 m

√289 m = 17 m

Step-by-step explanation:

Simply apply the formula

D=√(l²+b²+h²)

= √[(8m)²+(6m)²+(10m)²] ................ all are under the root

=✓[64m²+36m³+100m²]

=✓200m²

= 14.14m
