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 …
Degrees to Radians: Convert & Calculate
We use different measurement units to determine length (in, m, or km), mass (kg, mg, or g), or temperature (Celsius or Fahrenheit) and Math enables us to convert between these measurement units. In the same way, a circle’s angle can be measured in two ways: with degrees and with radians and using formulas, we can convert between the two. What …
Interval Notation: Writing & Graphing
Let’s learn how to write and graph interval notation. What is an Interval Notation? Interval notation is a way of writing solutions to algebraic inequalities. You may recall that inequalities are relations that compare non-equal mathematical expressions. The four inequality signs are: less than (<), greater than (>), less than or equal (≤), and greater than or equal (≥). Here …
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 …
Probability: Figuring Out the Odds
Let’s learn about basic probability. What is Probability? Probability is the likelihood of something to happen. It ranges between zero (0) or impossible to one (1) or certain and will never be less than 0 or more than 1. Probability can be expressed in fraction, decimal, or percentage. For example, here are some probabilities: A pig talking is 0 or …
Rectangular Prism: Surface Area & Volume
Let’s learn how to find the surface area and volume of a rectangular prism. What is a Rectangular Prism? Prisms are three-dimensional objects with two equal bases or ends, flat surfaces or sides, and the same cross-section along its length. A cube is a prism, but unlike a cube that has 6 equal square faces, a rectangular prism has six …
Linear Equations: Formula & Examples
Let’s learn about linear equations. What is a Linear Equation? A linear equation is the equation for a straight line. It’s a combination of constants and variables and is probably the simplest algebraic equations you’ll have to deal with. The standard form of linear equation is expressed in the formula:Ax + By + C = 0where A, B, and C …
Volume of a Cone: Formula & Examples
Let’s learn how to determine the volume of a cone. What is a Cone? A cone is a three-dimensional object that has a circular base; a vertex or top; a height which is the perpendicular distance from the vertex to the base; and a slant height which refers to the distance from the vertex to the side and down to …
