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. 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: Given that its base area is 2,928.9 square decimeters and its base perimeter is 275 decimeters, compute for the total. 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. An architect designed a triangular prism terrarium represented below. 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? In geometry, a triangular prism is a three-sided prism it is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding.Triangular Prism Formulas in terms of height and triangle side lengths a, b and c: Volume of a Triangular Prism Formulaįinds the 3-dimensional space occupied by a triangular prism. Significant Figures: Choose the number of significant figures or leave on auto to let the calculator determine number precision. Answers will be the same whether in feet, ft 2, ft 3, or meters, m 2, m 3, or any other unit measure.
Units: Units are shown for convenience but do not affect calculations. Seven hundred and ninety-two yards squared is the surface area of the larger triangular prism. Height is calculated from known volume or lateral surface area. Surface area calculations include top, bottom, lateral sides and total surface area. This calculator finds the volume, surface area and height of a triangular prism. It's a three-sided prism where the base and top are equal triangles and the remaining 3 sides are rectangles. B = side length b = bottom triangle base bĪ lat = lateral surface area = all rectangular sidesĪ bot = bottom surface area = bottom triangleĪ triangular prism is a geometric solid shape with a triangle as its base.
