Question

it takes an air pump 5 minutes to fill a twin sized air mattress (39 by 8.75 by 75 inches). how long will it take to fill a queen sized mattress (60 by 8.75 by 80 inches)?

Answer 1

It take 8.205 minutes to fill a queen sized mattress.

What is volume?

'Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

Given dimensions:

Twin sized air mattress (39 by 8.75 by 75 inches).

Queen sized mattress (60 by 8.75 by 80 inches)

Now, Volume of twin sized mattress

=39* 8.75* 75

= 25593.35 cubic inch

Volume of queen sized mattress,

=60* 8.75* 80

= 42000 cubic inch

as, To fill 25593.35 cubic inch it takes 5  minutes

so, to fill 1 cubic inch = 5/25593.35

and, So to fill 42000 cubic inch it will take = 42000* 5/25593.35

=8.205 minutes
