Area of a Trapezoid: Formula & Examples

Let’s learn how to find the area of a trapezoid. What is a Trapezoid? A trapezoid is a 4-sided flat shape with one pair of parallel sides called its bases. The height (also called altitude) of a trapezoid is perpendicular to its bases. The other two non-parallel sides are called legs. Examples of trapezoid-shaped objects are flowerpots, handbags, pails, and …

Area of a Hexagon: Formula & Examples

Let’s learn how to find the area of a hexagon. What is a Hexagon? A hexagon is a six-sided flat shape whose sum of interior angles is always 720°. If the hexagon has six equal angles and sides, it’s a regular hexagon. Otherwise, it’s an irregular hexagon. Regular polygons have apothem – the perpendicular distance from the hexagon’s center to …

Midpoint Formula: Equation & Examples

Let’s learn how to find the midpoint using the midpoint formula. What is a Midpoint? A line segment’s midpoint refers to the middle point that divides it into two equal parts. Finding the midpoint between two numbers simply means finding the average of those two numbers. For instance, if you have a line with endpoints at 2 and 10, its …

Volume of a Pyramid: Formula & Examples

Let’s learn how to determine the volume of a pyramid. What is a Pyramid? A pyramid is a three-dimensional solid with a polygonal base and triangular faces that intersect at a point called the apex (or vertex). Pyramids are classified according to the shape of their base. Regular pyramids, unsurprisingly, have bases that are regular polygons. Examples are triangular pyramids …

Area of a Triangle: Formula & Examples

A triangle is three-sided shape with a height that’s perpendicular to its base. There are different types of triangle, such as scalene, isosceles, and equilateral. The formulas for finding the area and the perimeter of a triangle are the same for all its types. Here’s an illustration of a showing the formulas for finding the area and perimeter of a …

Perimeter of a Triangle: Formula & Examples

A triangle is three-sided shape with a height that’s perpendicular to its base. There are different types of triangle, such as scalene, isosceles, and equilateral. The formulas for finding the area and the perimeter of a triangle are the same for all its types. Here’s an illustration of a triangle and the formulas for finding its area and perimeter. Want …

Area of a Square: Formula & Examples

A square is a shape with four equal sides (equilateral) and four equal angles (equiangular). It’s the only equilateral and equiangular quadrilateral. Here’s a quick guide to computing the area of a square. How to Compute the Area of a Square The area of a shape refers to the total amount of space enclosed in it. To find the area …

Perimeter of a Square: Formula & Examples

A square is a shape with four equal sides (equilateral) and four equal angles (equiangular). It’s the only equilateral and equiangular quadrilateral. Here’s a quick guide to computing the perimeter of a square. What is the Perimeter of a Square? As previously discussed, perimeter is the total length of a closed shape. To find the perimeter of a square, add …

Volume of a Cube: Formula & Examples

Let’s learn how to determine the volume of a cube. What is a Cube? The only regular hexahedron, a cube is a three-dimensional object with six equal-sized square surfaces or sides, 12 edges, and 8 vertices. Given that its square sides are equal, it follows that a cube’s length, width, and height are equal, too. Examples of cube-shaped objects are dice, …

Surface Area of a Cube: Formula & Examples

Let’s learn how to determine the surface area of a cube. What is a Cube? The only regular hexahedron, a cube is a three-dimensional object with six equal-sized square surfaces or sides, 12 edges, and 8 vertices. Given that its square sides are equal, it follows that a cube’s length, width, and height are equal, too. Examples of cube-shaped objects …
