Geometric Shape Formulas Flashcards
Basic Total Surface Area formula
TSA = LA + BA
BA- area of the base
- Surface area = total surface area
Area of a triangle
2
Area of an equilateral triangle
1/4b^2rad3
Basic Volume formula
V = Bh
B - area of the base
Volume of a triangular prism
V = 1/2bh(H)
Diagonals of a cube
X rad 3
LA of a cylinder
LA = 2|~|rh
|~| - pie
Two pies are heavy
Total surface area of a cylinder
TSA= 2|~|rh + 2|~|r^2
Two pies are heavy, two apple pies are too
LA of a regular pyramid
LA = 1/2LP
L-slant height
P-perimeter of the base
In a rhombus all sides are congruent
With diagonals:
A = d1 • d2
——-
2
LA of a cone
LA = |~|rL
SA of a cone
SA= |~|rL + |~|r^2
Frustum
Portion of a cone between the base and the parallel frame
Basic Lateral area formula
LA = BP • H
BP - base perimeter
H - height
SA of a cube
SA = 6s^2
