Transcript of APPLICATION OF MENSURATION IN DAILY LIFE

Example
Prism is a 3- D shape,
where the front and back
faces are two identical
polygons, and both polygons are connected by parallel lines.
These parallel lines will
ensure that a cross section ANYWHERE on the prism will yield the same identical polygon. 
Prism
Area of a square:
Because each side of a square is of equal length, you'll simply square the length of one side, called t.
Perimeter:
Sum of all sides = 4 x t
Quadrilateral- Square
Area of rectangle:
To find the area of a rectangle, you need 2 measurements: the width, or base and the length, or height.

Perimeter:
Sum of all sides : 2*(h+b)
 
Quadrilateral- Rectangle
A Quadrilateral is a geometrical shape enclosed by four
straight line segments
Quadrilaterals


We use measuring jugs to determine the volume of water, juices, and spices when following recipes
Spoons of different sizes are used to measure and add quantities of specific volume
mensuration
A pyramid has a base and triangular sides which rise to meet at the same point.
The base may be any polygon such as a square,
rectangle, triangle, etc. The general formula for the


Pyramid
Examples
Triangles can be of the following types
Scalene Triangle
Equilateral Triangle
Isosceles Triangle
Right -angled Triangle
A Triangle is a geometrical shape enclosed by three straight line segments. Every triangle has three sides and three angles, some of which may be the same.
Examples

Area:piπ*(radius*radius)
Perimeter:2π*pi*radius
The circle is a plane geometrical shape in which all points on the shape are equidistant from the center.
Area is a quantity that expresses the extent of a two dimensional surface or
shape in the plane. Area can be understood as the amount of paint necessary to cover the surface with a single coat.
Perimeter  is a path that surrounds an area.
The word comes from the Greek peri (around)and meter (measure).
The term may be used either for the path or its length - it can be thought
of as the length of the outline of a
shape. 


To find the quantity of timber
in a trunk with parallel
ends, the areas of a few
sections must be
calculated as accurately as possible.

To know how much
paint , wallpaper,
flooring, carpeting or
tile you may need for your project and
to know the area of the walls
In the forestry industry, it is used to
make a projection as to when a
group of trees will be ready to harvest
which can help in determining
how much wood would be available
for sale at any time.

Cube is just a special case of a cuboid where all the dimensions have same magnitude i.e. length = breadth = height.

Cuboid is a box-shaped object. It has six flat sides and all angles are right angles and all of its faces are rectangles
Cuboid - volume and T.S.A

Volume = pi*π r*r*h
T.S.A = 2π *pi*r(h+r)
Cylinder is similar to a prism, but its two bases are circles, not polygons. Also, the sides of a cylinder are curved, not flat.
Cylinder - Volume and T.S.A
V = ½(b*h*l)
V = ½ × 4 × 13 × 42
V = 1092 cm³
Volume of a Prism


Mensuration is the mathematical term for calculating the areas, volumes, length of sides, and other parts of geometric shapes, such as, triangles, quadrilaterals, circles, prisms, spheres, pyramids, cones, polygons, cylinders, etc., through the use of equations or formulas.
Definition
base = heptagon
base = pentagon
base = quadrilateral
A Pyramid has a base and triangular sides which rise to meet at the same point.
The base may be any polygon such as a square, rectangle, triangle, etc.
Some types :
The Area of a triangle is the space formed by its three sides. It is calculated by using the formula,
A = ½ (b*h)

The perimeter (P) of a triangle is the sum
of lengths of its three sides
P = a + b + c
Area & Perimeter
In general, a cone is a pyramid with a circular cross section. A right cone is a cone with its vertex above the center of its base.
