A letter formula for finding the perimeter, area, surface area, volume, volume, and cost-effective unit of volume for all graphics (elementary school)

1. Square: C perimeter S area a side length perimeter = side length ×4 C =4a
Area=side length×side length S=a×a
2. Cube: V: volume a: prism length surface area = prism length × prism length ×6
Table S = a×a×6
Volume=edge length×edge length×edge length V=a×a×a
3. Rectangle:
C circumference length S area a side length perimeter =(L+W)×2 C=2(a+b)
Area=L×W S=ab
4. Box
V: volume s: area a: length b: width h: height
(1) Surface area (L×W+L×H+W×H)×2 S=2(ab+ah+bh)
(2) Volume=L×W×H V=abh
5. Triangle
S area a bottom h height area = bottom × height ÷2 s = ah ÷2
Triangle height = area ×2÷ bottom
Triangle bottom = area ×2÷ height
6. Parallel quadrilateral: s area a bottom h height area = bottom x height s = ah
7. Trapezoid: s area a upper bottom b lower bottom h height
Area =(top + bottom)× height ÷2 s =(a+b)×h ÷2
8 Circular: S-plane C circumferential length ∏d=diameter r=radius
(1) Perimeter = diameter ×∏=2×∏× radius C =∏d =2∏r
(2) Area=radius×radius×∏
9. Cylinder: v volume h: height s: bottom area
R: bottom radius c: bottom perimeter
(1) Side area = perimeter of bottom x height
(2) Surface area = side area + bottom area ×2
(3) Volume = bottom area × height
(4) Volume=side area÷2×radius
10. Cone: v volume h height s base area
R Radius volume of bottom = bottom area × height ÷3
