What Is Pyramid? Is geometrical polygon-shaped base
and the establishment of a triangular field that intersect at one point. Intersection of the straight sides of the pyramid called cusp pyramid.
What Are The Example?
1 2 3 4
1. Triangular Pyramid
2. Rectangular Pyramid
3. Pentagonal Pyramid
4. Hexagonal Pyramid
Lines Of Pyramid
Triangular Pyramid has 6 lines Rectangular Pyramid has 8 lines Pentagonal Pyramid has 10 lines Hexagonal Pyramid has 12 lines
FORMULA
Determining The Lines of Pyramid
Lines = 2n
Where n is the type of the pyramid base. If the type of base on the pyramid is square, then n = 4. If the type of base on the pyramid is a triangle, then n = 3, and so on.
Side Of Pyramid
Sides of Triangular Pyramid
•Triangular Pyramid has 4 side
•The field of side: Triangle(4)
Sides of Rectangular Pyramid
Rectangular Pyramid has 5 side
The field of side: Triangle (4) Rectangle
(1)
Corners and Vertex
In the Triangular Pyramid, there are 9 corners and there are 4 vertex.
In the Rectangular Pyramid, there are 12 corners and there are 5 vertex.
FORMULA
Determining The Points of Pyramid
points = n + 1
Where n is the type of the pyramid base. If the type of base on the pyramid is square, then n = 4. If the type of base on the pyramid is a triangle, then n = 3, and so on.
Volume Pyramid
Surface Area
Surface area pyramid == Area□ ABCD + Area ∆ TAB + Area ∆
TBC + Area ∆ TCD + Area ∆ TAD
Luas Permukaan pada Limas = Luas alas + jumlah seluruh luas sisi

Question Volume of Pyramid
Base pyramid form a right triangle with sides of length 12 cm, 16 cm, 20 cm. If the pyramid height 21 cm, then the volume of the pyramid is....
Lalas = ½ x a x t
= ½ x 16 x 12= 96 cm²
Vlimas = 1/3 x Lalas x tLimas
= 1/3 x 96 x 21
= 672 cm³
ANSWER
Question Surface Area of Pyramid
Picture below is a rectangular pyramid.
ABCD with base side length of 6 cm
and 4 cm tall pyramid. Then the
surface area of the pyramid is ...
1. OF = ½ x AB = ½ x 6 = 3 cmTF² = TO² + OF²
= 4² + 3² = 16 + 9 = 25TF = √25 = 5 cm
Lp = Lalas + Lsisi tegak
= AB x BC + 4 x ½ x BC x TF
= 6 x 6 + 4 x ½ x 6 x 5
= 96 cm²ANSWER
