Question

6. The maximum length of a rod, that can be kept in a
rectangular box of dimension 8 cm x6 cm x 2 cm, is
(a) 2 13 cm
(b) 2V14 cm
(c) 2126 cm
(d) 10,2 cm​

Answer 1

Step-by-step explanation:

your answer is c

but i am not confirm

Answer 2

The maximum length of the rod that can be placed in a cuboid is 25.73 cm

Given,

dimensions of cuboid = 22.5 cm * 10 cm * 7.5cm

We know,

maximum length of rod = length of diagonal of the cuboid

Length of diagonal of cuboid is given as :

d = \sqrt{l^{2}+b^{2} +h^{2} }l2+b2+h2

where,

l is the length of the cuboid,

b is the breadth of cuboid and

h is the height of the cuboid

Substituting the values in the formula,

d = \sqrt{22.5^{2}+10^{2} +7.5^{2} }22.52+102+7.52

d = \sqrt{506.25+100+56.25}506.25+100+56.25

d = \sqrt{662.25}662.25

d = 25.73 cm

Hence,

The maximum length of the rod that can be placed in a cuboid is 25.73 cm
