1. ## air problem

How much air is enclosed in a tent with a rectangular base 4m by 2.7m
if the height is 5m?

the problem above has an answer from the book that has no solution shown and its answer is 18m^3...
but my answer is 54m^3 since l x w x h = formula of volume

Does your tent have sloping or vertical sides ?
5m high ? You'r catering for some very tall people !

Hello, rcs!

How much air is enclosed in a tent with a rectangular base 4m by 2.7m if the height is 5m?

You assumed that the tent is a rectangular "box".
If that were true, they could have described a room with those dimensions.
Why mention a "tent"?

I assumed it was a "traditional" tent shape.
Code:
                  *
*    \
*         \
/:\         \
/ :5\         *
/  :  \    *
* - - - *    4
2.7
But I got a different answer.

The only way that the volume could be 18 m3
. . is if the tent is a pyramid with a rectangular base.

It should have stated the shape of the tent.

But solving it with your sketch soroban it goes like
triangular prism then the answer is not 18 cm^3.. it is 27 cm^3
