What is a surface area?
The surface area of a three-dimensional solid with plane faces is the sum of the areas of the faces.
Surface area is the sum of the areas of the outside rectangle or how much paint we need to paint it from the outside.

What is a volume?
The volume of a solid is the amount of space it occupies.
Volume of this shape is for example how much water can fit inside

Volumes for prisms and pyramids
The volume of a prism is the area of the base multiplied by the height.
The volume of a pyramid is one third the area of the base multiplied by the height.

Real life dimensions of shapes
0 In the following slides I will be finding the real measurements of some shapes in real life such as
soccer fields, pyramids, coca cola can, basket ball and traffic cone.

Soccer field
To know how many a meters a player would run around the soccer field we calculate the perimeter
Perimeter = 120 + 120+ 90 +90 = 420mTo know how much grass needed to cover the field we use the area. Area = 90 x 120
=
L = 120m
W = 90m

Basket ball
Radius = 11.7 cmTo know how much air neededto inflate the ball we need to Calculate the volume. Volume =
To know how much leather was usedIn making the basket ball we need to Calculate surface area. Surface area =
r= 11.7cm

Coca Cola can
To know how much colacan fit inside the canwe calculate the volume.
Volume =To know how much aluminum wasUsed in making the closed can we Calculate the surface area. Surface area = I rounded the answerup to take into accountthe waste of material.
