Q:

How do you calculate gross floor area?

A:

Calculating the gross floor area requires you to know the area of the floors and the width of the interior walls. For the floors, you will need a tape measure and a calculator. To determine the wall width, you may need to contact the builder. The only rooms that aren't included are plazas or rooftops.

  1. Measure the floor area

    Measure the floor are by going through one room at a time. Measure both the length and width of each room. In the case of rooms that do not have a standard geometry, break the room up into smaller shapes and add the area. For example, consider a room that has a main section that is 10 feet wide and 10 feet long has a narrower section that is five feet wide and long. You would take the two areas, 100 ft^2 and 25 ft^2, and add them. Find the total area by adding all the room areas together at the end.

  2. Determine the length of the walls

    Use the tape measure and measure the length of the walls. Do this for the walls in each room.

  3. Determine the width of the interior walls

    Determine the width of the interior walls and multiply this with the length to determine the area. To do this, you may need to contact your builder or view schematics.

  4. Add all the areas

    Add all the areas up. This final number is the gross area.

    How to calculate square miles?

    A:

    To calculate the area of a structure or section of land mass in square miles, use the formula for area of the section's shape with the dimensions, such as length, width, and radius, in miles. Not all sections of land or buildings have a simple shape, in which case the section should be divided up into simple shapes as well as possible to get an exact answer or a good estimate.

    How do you calculate acreage from a perimeter?

    A:

    To determine the acreage from a perimeter, the perimeter measurements must offer sufficient information to deduce the area of the enclosed shape. The formula and necessary information differs depending on the shape. Acreage can be determined from any unit of length or area, although different conversion formulas are needed for metric units and imperial units of measurement.

    What do you do in a lockdown drill at school?

    A:

    During lockdown drills at school, students exit hallways, enter the nearest classroom, move away from windows and doors towards interior walls, and get out of the line of sight of the door, either on the floor or behind furniture. Teachers close and lock classroom doors, turn off the lights, pull down window shades and cover any windows on the doors. Everyone remains hidden and silent until the all-clear.

    What is the formula to calculate square feet?

    A:

    The formula to calculate the square footage of an area that is square or rectangular in shape is length multiplied by width equals the area's square footage. For example, if a rectangular shaped room measures 11 feet in length and 13 feet in width, 11 multiplied by 13 equals 143 square feet.
