Density is Weight per Volume so you measure the weight of the brick using a scale and find the volume by multiplying length by width by height and then divide the weight by the volume.
172 acres is 7,492,320 square feet. (43,560 sqft per acre).

Weight of 1 Kg Brick = 9.8 Newtons
Bricks come in different sizes. Multiply the total number of square feet by the size brick you are using. Then divided by .95 to allow for breakage.Size Brick Bricks per square footKing Size 4.80Builders Special 5.33Modular 6.85Colonial 4.90Queen Size 5.20

That depends on the volume of the brick. Whatever its volume is, its weight underwater is(weight of the brick in air) minus (weight of an equal volume of water)
The weight of the displaced water is 2/3 the weight of the brick. So the weight of the brick is 3/2 the weight of an equal volume of water ... just another way of saying that the density of the brick is 1.5 gm/cm3.
