Question

Find the diagonal length of this figure

Answer 1

Answer:

$5\sqrt{5} \:mm$

or

11.18 mm

Step-by-step explanation:

length of diagonal

$=\sqrt{l^{2} +w^{2}+h^{2} } \\=\sqrt{8^{2} +6^{2}+5^{2} } \\=\sqrt{64 +36+25 } \\=\sqrt{125 } \\=5\sqrt{5} \: mm\\=11.18 mm$

Answer 2

Answer:

the answer is,

11.18mm

by pythagoras theorem, you'll get base diagonal as 10mm, therefore the diagonal*marked red is 11.18mm.
