Answer 1

Answer:

Step-by-step explanation:

u will need to find hypotunse

(hyp)^2= (alt)^2 + (base)^2

x ^2 =  12 ^ 2  +  12 ^2

= 288

x = $\sqrt\\288$

x = 16.9 m

Answer 2

Answer:

$12 \sqrt{2}$

Step-by-step explanation:

given sides of cube - 12m

solutions -

diagonal-

$\sqrt{2 \: } \times side$

$\sqrt{2} \times 12$

$12 \sqrt{2}$

or 16.9m
