Two triangles
The perimeter of that rectangle is 89.6875.
No, it has four.
Oh, what a happy little challenge! To divide a rectangle into 8 parts using only 3 lines, you can start by drawing two lines that intersect inside the rectangle to create four sections. Then, draw a third line that intersects the other two lines outside the rectangle, creating a total of eight parts. Just like that, you've created a beautiful composition with just a few simple strokes.
An octagon has eight sides.
Side by side, they would form a rectangle. From part-side touching part-side through to corner to corner, they would form a shape somewhat like a figure of eight. There are other possibilities - eg corner of one touching the side of the other.
It's greater because if you draw to thin rectangles and divide one into tenths and one into eighths. First color in three eighths. Then in the other rectangle color in eight tenths. Then what shaded rectangle has the greatest amount. The One with the greatest shaded amount is larger so so... eight tenths is greater then three eighths.I hope that helped :)
A 3d rectangle, or a cuboid, has eight corners.
An octagon
Eight.
1 third divide 6 eight = 0.16666666666666666
A rectangle has four vertices, while a rectangular prism has eight vertices. In a rectangular prism, each of the four corners of the rectangle forms a vertex, and there are corresponding vertices at the opposite face, totaling eight.
