To adequately light a 1,000 square foot space, you typically need between 50 to 100 lumens per square foot, depending on the purpose of the space. This means you would need approximately 50,000 to 100,000 lumens in total. For example, areas requiring more light, like kitchens or workspaces, may need closer to the higher end, while living rooms may require less. Always consider the type of lighting and the desired ambiance when calculating lumens.
1000 sq ft should do it
Da-Lite, the projector screen company has a great calculator here and even includes a brand and model reference.
22.96 acres.
2*(5280 ft.) - 1000 ft. = 9560 ft.
1000 sq metes = 10764 sq ft.
To determine the volume of air needed to float an object, you need to know the density of air and the weight of the object. For example, if the density of air is approximately 0.075 lb/ft³, then to float a 1000-pound object, you would need approximately 13,333.33 ft³ of air (1000 lb / 0.075 lb/ft³ = 13,333.33 ft³).

Answer: 1000 ft² = 0.022956 acres.
Math says 4 1/2 4"x8" bricks are needed to cover 1 sq. ft. So 9 bricks will cover 2 sq ft. That needs to happen 500 times so you need 9x500 or 4500 bricks sized 4"x8" to cover 1000 sq ft.
