Picture Of Me and My Object “Pyramid”
Definition A polyhedron in which the base is a polygon and the lateral faces are triangles with a common vertex.
Why I chose this Object I chose this object because I wanted to be different. I wanted to try something new, considering everyone in the class chose the “cube”. I wanted to challenge myself by picking something that I didn’t know that much about.
Concept 1 Volume- The measure or size of a three-dimensional object or region of space independent of its shape.
Example of Concept 1 Volume V= 1/3Bh Where B= the base and h= the height V = (5cm x 5cm) x 3 cm Volume = 25 cm3
Concept 2 Surface of Area- A set of points forming the boundary of a geometric figure.
Example of Concept 2 Surface Area S=B+1/2P l Where B= the base, P= the perimeter, and l = the slant height
Concept 3 Pythagorean Theorem- A theorem stating the square of the length of the longest side of a right triangle is equal to the sum of the squares of the lengths of the other sides.
Example of Concept 3 Pythagorean Theorem a^2+b^2=c^2 By Pythagoras' Theorem from right-triangle VOM, we have
