$420$ $cm$

if each small part is $35$ $cm$ , and there are three of those, multiply $(35)(3)$ OR add $35+35+35$

you get
$105$

you now multiply $(105)(4)$ OR add $105+105+105+105)$ because that piece was one of four pieces

you get
$420$ $cm$
(don't forget to add the unit!)

TO CHECK, divide

$420$ divided up into $4$ pieces
$(420/4)$

you get
$105$

that piece is then cut up into $3$ smaller pieces, so divide $105$ by $3$
$(105/3)$

you get
$35$
