You need just two measurements: the diameter of the base and it's height, but the calculus is more involved than most of the other simple bodies. The surface area of a cone is one of the most complicated and it is where the need for a calculator becomes more apparent. The surface area formula for a cone, given its diameter (or radius) and height is π x (diameter / 2) 2 + π x (diameter / 2) x √ ((diameter / 2) 2 + (height 2)), where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is π x radius 2 + π x radius x √ (radius 2 + (height 2)), as seen in the figure below: To find the SA simply multiply 4 times 3.14159 times the radius square. π is, of course, the well-known mathematical constant, about equal to 3.14159. Visual on the figure below:Ī sphere's surface area can be calculated just by knowing its diameter, or radius (diameter = 2 x radius). The surface area formula for a sphere is 4 x π x (diameter / 2) 2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 x π x radius 2. to find the surface area of a cube with a side of 3 inches is to multiply 3 x 6 = 18 square inches. side 2 is the surface of one of the sides, and since the cube has 6 equal sides, multiplying by 6 gives us the total cube surface area. This calculation requires only one measurement, due to the symmetricity of the cube. The surface area formula for a cube is 6 x side 2, as seen in the figure below: The result from our surface area calculator will always be a square of the same unit: square feet, square inches, square meters, square cm, square mm. In all surface area calculations, make sure that all lengths are measured in the same unit, e.g. Below are the formulas for calculating surface area of the most common body types. How to calculate the surface area of a body?ĭepending on the type of body, there are different formulas and different required information you need to calculate surface area (a.k.a. How to calculate the surface area of a body?.The volume of Prism = Area of the Base × Height of prism The volume of the triangular prism is equal to the product of the area of the triangular base and the height of the prism. For these computations, we need the height, side and base length of the prism. The surface area of a triangular prism is the amount of covered space on the outside surface of the prism. The volume of a prism is the space within the triangular prism. These are Prism volume and Area of prism formulae. Prism formula includes two very important formulae. Volume and Surface Area of Triangular Prism: Also, the number of triangular prism edges is 9. The net of a triangular prism is made up of rectangles and triangles. The net of a solid figure is possible when a solid figure is unfolded along its edges and further its faces are laid out in a pattern in two dimensions. All the cross-sections parallel to the base faces are triangle. How to find the surface area of a triangular prism with a rectangular base. The rectangular sides of this prism are rectangular in shape and are joint with each other side by side. How to find the missing length of a rectangular prism with surface area. The edges and vertices of the bases are connected with each other. It is a pentahedron with nine distinct nets. According to the nature of prism, the two triangular bases are parallel and congruent to each other. It is having two triangular bases and three rectangular sides. 2 Solved Examples for You Triangular Prism DefinitionĪ triangular prism is a popular polyhedron.
