Can I fit a mattress into a tent?

Question

This is a real world problem I am trying to figure out! I am camping out with a tent and inflatable mattress. But the mattress needs to be inflated outside of the tent (since the air pump has to be plugged in, and the only outlet available is nearby but not close enough. So I need to 1) erect the tent, 2) inflate the mattress, then 3) get the mattress into the tent. The manufacturer says the tent opening is 130.5 cm tall and 130 cm wide. The mattress is 54" wide and 13" high. Assuming I have to slide it in diagonally, will it fit? Thank you!!

Answer 1

Convert the mattress dimensions: (54 in)(2.54 cm/in) = 137.2 cm, (13 in)(2.54 cm/in) = 33.0 cm. The mattress diagonal d is obtained from d² = 137.2² + 33.0² and d = 141.1 cm. The tent opening o² = 130² + 130.5² and o = 184.2 cm. Yes, the mattress will easily fit through the opening.
