How many vertices does an octagonal pyramid have?
An octagonal pyramid has 9 vertices. The base of this shape is an octagon, which will give it 8 vertices when the triangles that form the sides are considered. Those triangles will lead up to the apex (top) of the pyramid, and that will be the 9th vertex.
What is the area of a rectangle mm by mm?
Area of rectangle is lenth by breath.So mm by mm will give area of mm square.
How do you divide rectangle into 4 equal parts?
Many ways: Join the opposite vertices; Join the midpoint of each side to the midpoint of the opposite side; Draw three lines parallel to one of the sides at distances of a quarter, half and three-quarters of the width. Then there are ways that give equal but non-congruent parts.
How many number of angles for an Octahedron?
32* * * * *An octahedron is a generic term for a polyhedron with eight faces. There are a number of different configurations and these will give rise to a different number of vertices. Some examples:Heptagon based pyramid: 8 vertices, 28 angles.Hexagon based prism: 12 vertices, 36 anglesQuadrilateral based dipyramid: 6 vertices, 24 angles.
The area of a rectangle is 450 square inches if the length of the rectangle is 24 inches what is is the width?
In getting the area of a rectangle, the formula is length x width.Given the length 24 and the area 450:450 divided by 24 will give you 18.5.length - 24width - 18.5area - 450Checking:24 x 18.5 = 450
