Answer:
yes (see below)
Step-by-step explanation:
Use diagonal of a cuboid equation: [tex]\sqrt{l^2+w^2+h^2} [/tex]
where l is the length, w is the width and h is the height
[tex]\sqrt{l^2+w^2+h^2} =\sqrt{3^2+1^2+2^2} =\sqrt{14} [/tex] ft
[tex]\sqrt{14} [/tex] x 12 = 44.90 inches
As 42 < 44.90, the umbrella can be packed in the suitcase.
