A room measuring 20' x 20' = 400 square feet
20 x 25 = 500.... so there are 500 square feet in an area 20 foot by 25.

To calculate the number of 2x4x8 studs needed for a 20x20 building, consider that each wall will need studs spaced 16 inches apart. For a 20-foot wall, that requires approximately 15 studs per wall (including corners). Since there are four walls, you would need about 60 studs. However, it's important to account for additional studs for doors, windows, and any framing needs, so a safe estimate would be around 70-80 studs.

The studs themselves are torqued to about 45 foot pounds. The nuts are torqued to 20 foot pounds.
To determine the number of cement blocks needed for a 20-foot by 30-foot building, you'll first need to calculate the total wall area. Assuming an 8-foot wall height, the perimeter is 100 feet (20+30+20+30), resulting in a wall area of 800 square feet (100 feet x 8 feet). If each standard cement block is approximately 1.125 square feet, you would need around 711 blocks (800 ÷ 1.125). This estimate does not account for doors, windows, or other architectural features.
The maximum weight that studs can hold depends on their size and material, but typically they can support between 20-50 pounds per linear foot. To ensure that studs are properly supported, use appropriate anchors or screws, distribute weight evenly, and avoid overloading the studs.
