1
Area and Volume Area is the amount of space contained in a two-dimensional figure Volume is the amount of space in a three-dimensional figure
2
Squares and Rectangles
Remember, the area of a square or rectangle is given by π΄=πππππ‘β π₯ π€πππ‘β A square is a rectangle with four equal sides Find the area of the following rectangle: The three-dimensional version of a square or rectangle is called a rectangular prism (different side lengths) or a cube (same side lengths)
3
Triangles Recall that the area of a triangle is given by π΄= 1 2 πββ
Find the area of the following triangles, using the formula: A three-dimensional figure with a square base and triangular faces is called a pyramid
4
Area and Volume Area!
5
Representing 3-d Figures: Nets
A βnetβ is used to represent a three-dimensional shape on a two-dimensional piece of paper
6
Volume of a Prism To calculate the volume of a prism, multiply the area of the base by the height Or, Volume = length x width x height
7
Volume of a Pyramid Finding the volume of a pyramid, multiply the area of the base times height, then multiply by one-third π΄πππ= 1 3 βπ΄πππ ππ π΅ππ π βπ»πππβπ‘ Or, π΄πππ= 1 3 βπβπ€ββ
