well to calculate the width of a classroom you have to measure the width of each wall and then add up all of the measurements you found out and then that will be the width of the classroom. i hope this helps :) :) :) :) :)
You can calculate the volume by multiplying height, width, and mass. Then, divide the mass by the density to find the volume. Finally, calculate the length by dividing the volume by the height and width.
To calculate volume simply do length x width x height
Multiply the height by the width
36 inch
Multiply the width times the height.
length x width = area
length, width X height.
Length times width.
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
The width could be virtually anything. If you are wanting to find out how to calculate width, you need to have more information in addition to length.
By multiplying its length to its width. Area= length x width
