1, squared: c perimeter s area a side length perimeter = side length× 4c = 4a area = side length× side length s = a× a.

2. Cube: v: volume A: side length surface area = side length × side length× 6s table =a×a×6.

Volume = side length × side length × side length v = a× a× a.

3. Rectangular:

C perimeter s area a side length perimeter = (length+width) ×2 C=2(a+b) area = length × width S=ab.

4. Cuboid

V: volume s: area a: length b: width h: height.

(1) surface area (length× width+length× height+width× height )× 2s = 2 (AB+ah+BH)

(2) volume = length× width× height V=abh

5. Triangle

S area a bottom h height area = bottom x height ÷2 s=ah÷2.

Height of triangle = area ×2÷ base.

Triangle base = area ×2÷ height

6. parallelogram: 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 = (upper bottom+lower bottom) × height ÷2 s=(a+b)×h÷2.

8 circle: s plane, c circumference ∏ 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 circumference.

(1) Transverse area = bottom circumference × height.

(2) Surface area = lateral area+bottom area ×2

(3) Volume = bottom area × height

(4) Volume = lateral area ÷2× radius.

10, cone: v volume h height s bottom area r bottom radius volume = bottom area x height÷ 3.
