What is the surface area and volume of a triangular-based pyramid?
Volume_any_pyramid = 1/3 × area_base × perpendicular_height For a triangular pyramid (tetrahedron) this becomes: volume = 1/6 × base_width × base_height × pyramid_height For the surface area there is no (easy) general formula: the area of the base triangle and the area of the three side triangles need to be worked out and added together.
What is the formula to calculate surface area of a 90 degree elbow?
The formula to calculate the surface area of a 90-degree elbow is A = πDL, where A is the surface area, D is the diameter of the elbow, and L is the centerline radius. The surface area of the elbow is essentially the curved surface area of the elbow pipe fitting. This formula is derived from the mathematical principles of geometry and calculus, specifically the surface area of a cylinder.
What is the formula of surface area of a rectangle?
Length x Width x Height = surface area
What is a formula to work out the surface area of a quadrilateral?
A quadrilateral does not have a surface area because it is not a voluminous figure.
How do you do formula for surface area using sphere?
Surface area of a sphere = 4*pi*radius2
