How do you calculate linear feet?

The construction industry uses linear feet to distinguish it between square feet, cubic feet or others. For instance, purchasing ceramic tiles requires using square feet. However, buying a tile border uses linear feet since the width of the border is irrelevant. Another example is the term board-foot, which is commonly used in the lumber industry. This is equivalent to the volume of a 1-foot length of board that is 1 foot wide and 1 inch thick. The thickness and width are both important factors for manufacturers and purchasers of wood.\n\n\nThe archiving industry also often uses linear feet t..

How many edges does a cube have?

The surface area of a cube is determined by finding the area of one square by multiplying its length times its width, or by squaring the length of one side, and then multiplying that product by six for each one of the squares. Finding the volume of the cube requires multiplying its length times its width times its height or by cubing the length of one side.

How do you find the surface area of a pyramid?

Pyramids that have bases of different polygons have different formulas for finding the surface area. A regular hexagonal pyramid's surface area covers a hexagon for a base and six triangles of equal size. The total surface area is the area of the base plus six times the area of each triangle. This formula is SA=(1/2)a x P+(1/2)Pl where a is the length from the side of the hexagon to the center, P is the number of sides (6) and l is the product of the base times the triangle height.\nOther types of pyramids include irregular pyramids that have bases with different lengths and oblique pyram..

Is 33 a prime number?

The number 33 is what mathematicians call a composite number. A composite number is any number that has more factors than itself and 1. The only whole number that is not prime or composite is the number 1. Because 33 is a composite number, it has a prime factorization or a set of factors that are all prime.\nTo find the prime factorization of a number, divide by the smallest prime numbers first. Since 33 is odd, it does not divide by 2, but is does divide evenly into 3 x 11. Since 11 is also prime, this means the prime factorization of 33 is 3 x 11.

What is the least common multiple of 24 and 42?

A common way to solve for the least common multiple is to multiply the set of numbers together and divide by their greatest common divisor. The product of 24 and 42 is 1,008, and the greatest common divisor is 6, so the least common multiple is 1,008 / 6, or 168. While there are multiple ways to calculate the least common multiple, this method always yields the lowest figure.

How do you calculate the circumference of a circle?

Measure the radiusMeasure the distance from the center of the circle to the circumference. This is the radius of the circle. Calculate the diameterMultiply the radius of the circle in question by two to get the diameter.Calculate the circumferenceMultiply pi by the diameter to get the circumference of the circle. For instance, if the diameter of the circle is 20 centimeters, the circumference of the same circle is the product of 20 centimeters and 3.14, which is 62.8 centimeters.

What are some examples of two dimensional shapes?

The closest one can come to actually seeing a two dimensional shape is by looking at a paper cut out of one. The paper has thickness, however, so even these shapes are technically three dimensional. Three-dimensional shapes, such as cubes, pyramids and spheres, can be measured in the three dimensions of length, width and depth.\nSome two dimensional shapes are known as polygons. A polygon is a shape with three or more straight sides that is closed. Triangles, squares and pentagons are classified as polygons. A polygon cannot have rounded sides, like a square, or intersecting sides, like an hou..

Is a square a polygon?

A square has four angles and two diagonals. The diagonals of a square bisect each other and are equal in length. In a square, all four sides are equal in length, and all four angles are right angles. A polygon is named according to the number of sides it has. A polygon with four sides is called a quadrilateral. Similarly, a polygon with five sides is called a pentagon, and one with six sides is called a hexagon.

What is half of a sphere called?

Hemispheres are everywhere. The Earth is the common example of a hemisphere. As a cylindrical body, the Earth is sectioned into four separate hemispheres – North and South and East and West. The human brain is often broken down into the cerebral hemispheres.The Earth’s hemispheres naturally divide into seasonal opposites. The Northern Hemisphere, due to the tilt toward the sun, experiences summer from June through September and the Southern Hemisphere is in summer from December through March.

What are the applications of geometry in real life?

Another example of geometry used in everyday life would be in providing a home for fish. A fish tank needs to be filled carefully so that it does not overflow and so that it is at the right capacity to sustain the fish. To determine the appropriate amount of water to be used, a person must use basic geometry.Yet another example of geometry used in everyday life would be wrapping a gift. When a person is wrapping a gift, they must determine the appropriate amount of gift wrapping to use in order to wrap the gift in the best possible way. This requires a use of geometry to determine the best sha..
