Find the length of a diagonal of a cuboid whose dimensions are 12 m, 10 m and 8 m. (up to one decimal point)

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 17.54 m.

Diagonal = l2 + b2 + h2 

Diagonal = 122+102+82\sqrt{12^2 + 10^2 + 8^2}  = 144+100+64\sqrt{144 + 100 + 64}  = 308\sqrt{308}  = 17.54
