How many common red house bricks does it take to weigh in at exactly one ton? Please specifiy with or without holes.

There is a whole range of correct answers, as there is variation in the size of bricks and quality of the clay from which they are made.

The table on this page shows the weight of 1000 bricks of various types/sizes in Cwt (20 cwt = 1 ton.)

Ignoring the smaller, lighter clinker bricks, we find 1000 bricks weighing between 2,5 and 4.5 ton.

It really depends on the size of the bricks. Are these 667 3-pound bricks or 400 5-pound bricks, or bricks of any other weight? Are we talking about tons in American measurements or in metric?

In most of the Western States common bricks measure about 8½x4 1/8x2½ inches... The weight of bricks varies considerably with the quality of the clay from which they are made, and also of course with their size. Common bricks average about 4½ pounds each...

2000 lbs. ÷ 4.5 lbs. = 444 bricks

The 'standard' brick varies in external dimensions between countries, as well as across time. And some are solid, while others are frogged, perforated, cellular or hollow. Two bricks of the same size made from different clay will not necessarily have the same weight, due to differing density. All of these factors mean that no EXACT answer is possible without a more precise specification of the brick.

And these people produce bricks with weights ranging from 2.6 to 3.0 kg (roughly 5.7 to 6.6 lb). Using a metric ton this time (1000 kg, roughly 2200 lb), the number of bricks in a ton would be between 333 (for the heaviest ones) and 385 (for the lightest ones).
