What are 2 and 3 dimensional figures?
A point is 0-dimensional ... it has no length, breadth or height. A line is 1-demensional ... it has length, but no breadth or height. A square, circle, triangle etc is 2-dimensional ... each of them have length and breadth, but no height A cube, cylinder, sphere etc is 3-dimensional ... each of them have lenght, breadth and height.
What is the surface area formulas for prisms?
Surface Areas of Prisms Cube: 6 x breadth x Height Triangular Prism: (Breadth x Height) + (3 x Length x Breadth) Square Pyramid: (2 x Breadth x Height) + (Breadth x Breadth) Cylinder: (2 x Pi x radius x Length) + (2 x Pi x Radius x Radius) Cone: (Pi x Radius x Height) + (Pi x Radius x Radius) Sphere: Pi x Radius x Radius x 4 By Austin from a Christian school in Belrose, NSW
What is the area of square shape?
The area of any rectangular shape, including the square, is the length times the breadth. Area = length x breadth
How do you find breadth using perimeter and length?
If the shape is a rectangle (or square), then Perimeter = 2*(Length + Breadth) So Breadth = Perimeter/2 - Length
General formula for the volume of all prisms?
Volume of a Cube Length x Breadth x Height Volume of a Triangular Prism (Length x Breadth x Height) divided by 2 Volume of a Square Pyramid (Length x Breadth x Height) divided by 3 Volume of a Cylinder (Pi x Radius x Radius x Length) Volume of a Cone (Pi x Radius x Radius x Height) divided by 3 Volume of a Sphere (Pi x Radius x Radius x Radius x 4) divided by 3 -----=-----=-----=-----=-----=-----=-----=-----=-----=-----=-----= By Austin From Covenant Christian School
