Establish a side of the small square as s and write the formula 3s x 4s = Area. But L = 4s and W = 3s, so our formula becomes
AREA OF A CROSS SECTION
The cross section of an object is a plane figure established by a plane cutting the object at right angles to its axis. The area of this cross section will be the area of the plane figure produced by this cut. The area of the cross section is L x W. The most common units are square inches, square feet, square yards and in roofing, "squares."
COMMON CONVERSIONS 1. To convert square inches to square feet, divide square inches by 144. 2. To convert square feet to square inches, multiply by 144. 3. To convert square feet to square yards, divide by 9. 4. To convert square yards to square feet, multiply by 9. 5. To convert square feet to squares, divide by 100. Example: 1. Convert 1,550 square inches into square feet.
2. Convert 15 square feet to square inches.
4. Convert 10.3 square yards to square feet. 10.3 square yards x 9 square feet= 92.7 square feet 5. Convert 17,250 square feet to squares.
