This calculator lets you find out how much a rectangular box (e.g. a brick, book, door, companion cube etc) weighs based on its size and density. It can also find an object density provided you know its volume and weight. For example, if you have a brick that has dimensions of 92 x 57 x 203 millimeters and a density of 2.4 kg/L, you'd find out that the weight of that object is 2.555kg.

Volume and density calculators deal with problems related to this. The concrete calculator lets you calculate how many bags of concrete you need, while the brick calculator answers the question: how many bricks do I need?.
