You are framing a rectangular print that is 10 inches wide and 34 inches long. this wall space has an area of 640 square inches. what is the width of the frame so that the framed print fits perfectly in this location?

Assume you have a rectangular area such as a room and, for example, you want to calculate the square footage area for flooring or carpet. The way to calculate a rectangular area is by measuring the length and width of your area then multiplying those two numbers together to get the area in feet squared (ft2).

Instructions

1. Measure the rectangle length, width and height. For example, 8 inches long, 6 inches wide, 10 inches high.
   
2. Multiply the length by the height, then double the product. With this example, 8 inches multiplied by 10 inches results in 80 square inches, which multiplied by 2 equals 160 square inches.
   
3. Multiply the width by the length, then double the product. With this example, 6 inches multiplied by 8 inches equals 48 square inches, which multiplied by 2 equals 96 square inches.
   
4. Multiply the height by the width, then double the product. With this example, 10 inches multiplied by 6 inches results in 60 square inches, which multiplied by 2 equals 120 square inches.
   
5. Sum the amounts from Steps 1 through 3 to find the rectangle surface area. So adding 160, 96 and 120 square inches results in 376 square inches.
   

1 Us gallon is 231 cubic inches

If you are working this as a simple math problem, here is the solution. Each block is 8" x 16", which is an area of 128 square inches. A square foot is 144 square inches (12 x 12). Thus 185 square feet equals 185 x 144 or 26640 square inches. TO determine the number of blocks required, we divide the block size in square inches into the total area 26640/128 = 208.125. Thus, it would take 209 blocks to do the job. 209 blocks at $1.22 each = $254.98.

Now, if you are REALLY doing this job and need an accurate cost, you need to specify what the actual height and width of the area is to properly determine the number of blocks because 185 square feet can be any rectangular shape and may not come out to an even block height or width. Thus, the cost may vary considerably.

Measure the length and width of each wall, and then add up the resulting answers. So, if a wall is 9' tall and 12' wide, it is 108 sq feet. If another wall is 9' tall and 11' wide, it is 99 square feet. Your total would now be 99 + 108 or 207 square feet.

If you are doing it in feet and inches, you have to covert the inches to feet by dividing them by 12, since there are 12' in a foot. So with 3", divide 3 by 12 and get 0.25.

Calculating the cubic feet of a space requires multiplying the area of the bottom times the average height. You get the bottom area by multiplying the length times the width. Remember, to get cubic feet, you need all your measurements in feet to start with.

Here is your formula:

VOLUME (in cubic feet) = Length (in feet) X Width (in feet) X Height (in feet)

If it's a rectangular room you're working with, it is all straightforward. If there are irregular walls, it may be necessary to divide up the room into rectangular sections and then add together their individual volumes. If the ceiling is sloped, you need to use the height that has the same ceiling area above it as below it. Good luck! Truly.

I thought maybe you have the paper size set to Landscape rather than Portrait. If not, then you might look at:

I did some searching on that site and it yielded the hlep below which may give you some help.


Issue: How do I set my printer so my printout fits the paper size I am using?
Solution: Use the recommended Print Area MP240

Printing Area To ensure the best print quality, the machine allows a margin along each edge of media. The actual printable area will be the area inside these margins.
Recommended printing area (dark blue):
Canon recommends that you print within this area. ()
Printable area (light blue):
The area where it is possible to print. ()
However, printing in this area can affect the print quality or the paper feed precision.

Note
Borderless Printing
By selecting the Borderless Printing option, you can make prints with no margins.
When performing Borderless Printing, slight cropping may occur at the edges since the printed image is enlarged to fill the whole page.
For Borderless Printing, use the following paper.
- Glossy Photo Paper "Everyday Use" GP-501
- Photo Paper Glossy GP-502
- Photo Paper Plus Semi-Gloss SG-201
- Photo Paper Pro Platinum PT-101
- Photo Paper Plus Glossy II PP-201
-Photo Paper Pro II PR-201
- Matte Photo Paper MP-101
Performing Borderless Printing on any other type of paper may substantially reduce printing quality and/or result in printouts with altered color hues.
Borderless Printing on plain paper may result in printouts with reduced quality. Use them only for test printing. You can perform Borderless Printing on plain paper only when printing from your computer.
Depending on the type of paper, Borderless Printing may reduce the print quality at the top and bottom edges of the paper or cause these parts to become smudged.
