Never knowingly over-filled?

This is a box of Waitrose cookies, opened out.

The cookies in the photo on the box are about

1.17 (or 1 and one-sixth) as wide as the real thing.

So their volume is about 1.17 x 1.17 x 1.17 as large

as the real thing,

ie about 1.6 times the real thing,

ie more than half as big again as the real thing.

Estimate how many cookies there are in a 'full' box.

- fifteen?

- twelve?

- ten?

- no, just seven.

Is this stated on the box? No, only that the net weight is 150g.

The biscuits cost £1.80, or £1.20 per 100g,

so smaller and fewer and more expensive biscuits than one might expect.

Gulp*!*

Never mind.

Their 'Maryland' chocolate chip and hazlenut biscuits cost only 69p per 100g (or 57p at Sainsbury's).
