A) \( \Large 2\sqrt{13} cm \) |
B) \( \Large 2\sqrt{14} cm \) |
C) \( \Large 2\sqrt{26} cm \) |
D) \( \Large 10\sqrt{2} cm \) |
C) \( \Large 2\sqrt{26} cm \) |
Length of largest pencil that can be kept in a box
= Diagonal of box = \( \Large \sqrt{l^{2}+b^{2}+h^{2}} \)
where, l = 8 cm, b = 6 cm, h = 2 cm
= \( \Large \sqrt{64 + 36 + 4} \)
= \( \Large \sqrt{104} = 2\sqrt{26 cm} \)
