To calculate the square footage for waterproofing a chimney, first measure the height and width of each side of the chimney. Multiply the height by the width for each side to get the area, and then sum the areas of all sides. If the chimney has a cap or crown, include that in your calculations by measuring its length and width as well. Finally, add a little extra to account for overlaps and seams in the waterproofing material.
Length times width. 10x12 room is 120 sq. ft.
1 width times 1 length and divide by 9. Width times length gives you square footage, 9 sq. ft. in 1 sq. yrd.
The first thing you will need to do is measure the square footage of the area. Once you know the square footage figure on average $50 per sq foot.
To calculate square footage you need to multiply the length by the width. L x W = Sq.Ft.
