Given , Length = 10 cm

breadth = 12 cm

height. = 8 cm

.

Diagonal of cuboid = \sqrt{ l²\:+\:b²\:+\:h²}

\Longrightarrow\:\:\sqrt{ (12)²\:+\:(9)²\:+\:(8)²}

\Longrightarrow\:\:\sqrt{144\:+\:81\:+\:64}

 \Longrightarrow\:\:\sqrt{289}

 \Longrightarrow\:\:\fbox\orange{17\:cm}

.

.°. The Diagonal of the box = 17 cm

Hence, the maximum length of the pencil is = 17 cm

Explanation:

Given , Length = 10 cm

breadth = 12 cm

height. = 8 cm

Diagonal  of  cuboid = \sqrt{ l²\:+\:b²\:+\:h²} l²+b²+h²

\Longrightarrow\:\:\sqrt{ (12)²\:+\:(9)²\:+\:(8)²}⟹ (12)²+(9)²+(8)²

\Longrightarrow\:\:\sqrt{144\:+\:81\:+\:64}⟹ 144+81+64

\Longrightarrow\:\:\sqrt{289}⟹ 289

\Longrightarrow\:\:\fbox\blue{17\:cm}⟹17cm

.°. The Diagonal of the box = 17 cm

Hence, the maximum length of the pencil is = 17 cm
