Length of the parallelogram side
As you know, a parallelogram is a quadrilateral whose opposite sides are parallel. This is all that most people remember from the school course. However,…
Cone area
The first step in determining the surface area of a cone is to measure the radius of the circle, part of the cone. Next, you…
Regular polygon area
To find the area of a regular hexagon or any regular polygon, we use a formula that says area = half the product of apotema…
Truncated cone area
A truncated cone is a shape obtained by cutting a cone with a plane parallel to the base and not containing a vertex. The height…
Regular prism area
A prism is a polyhedron, two faces of which are congruent (equal) polygons lying in parallel planes, and the other faces are parallelograms that have…
Area of a parallelepiped
A parallelepiped is a three-dimensional shape with six faces bounded by three pairs of parallel planes, so all of its faces are parallelograms. Essentially, it…
Find the area of a cube
A cube is a simple shape, and it would be reasonable to assume that there is a simple formula for calculating its surface area. All…
Tetrahedron area
A pyramid on a triangular base is called a tetrahedron. In other words, a tetrahedron is a shape bounded by four triangular faces. Obviously, a…
The length of the sides of the rectangle
A rectangle is a quadrilateral with all angles equal to 90 degrees. Find the side length of a rectangle by knowing the diagonal and the…
Equilateral triangle side length
An equilateral, or conformal, triangle is a regular polygon with three sides, the simplest of regular polygons. All sides of a regular triangle are equal…
