Question

The diagram shows a 3cm x 5cm x 4cm cuboid.find the length ac

Answer 1

But where is the diagram...

Answer 2

/* Incomplete question */

/* It may be like this */

$\underline { \pink { Dimensions \: of \:a \:Cuboid : }}$

$Length (l) = 3 \:cm$

$Breadth (b) = 5 \:cm \:and \: Height (h) = 4 \:cm$

$\boxed { \blue { Diagonal = \sqrt{ l^{2} + b^{2} + h^{2} } }}$

$\red { Length \:of \: AC } \\= \sqrt{3^{2} + 5^{2} + 4^{2}} \\=\sqrt{9+25+16} \\= \sqrt{50} \\= 5\sqrt{2}\:cm$

Therefore.,

$\red { Length \:of \: AC }\green { = 5\sqrt{2}\:cm }$
