Is it 216
12X18
To purchase a 12x18 picture frame (in a variety of colors) one can go to a local photo shop. Another option is to purchase online from Sears, Amazon, or Picture Frame.
12x18+3=219 I believe
2x108 3x72 4x54 6x36 8x27 9x24 12x18 18x12
216 square feet. Length x width = square feet.
12 inches x 18 inches. This equals 216 square inches.
You can use two cake recipes for that size pan.
(12-ft x 18-ft) = (4-yd x 6-yd) = 24 square yards
216 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
Any large picture frame that's at least 12x18" will work well, though it depends on the size of one's family.
Depends on how big you cut the pieces. If you cut 2x2 inch pieces, a 12x18 cake will yield 54 servings.
that depends. if you want a longer poster then the height is 18. if you want a shorter poster that is wider you want to use 12 as your height.
