Perimeter, Area, Volume & Surface Area Formulas

Flashcards summarizing key perimeter, area, volume, and surface-area formulas for common 2-D and 3-D geometric figures.

Perimeter = 4s

Area = s²

Square

Perimeter = 2l + 2w

Area = lw

Rectangle

Perimeter = a + b + c

Area = ½bh

Triangle

Perimeter = 2b + 2h

Area = bh

Parallelogram

Perimeter = a + b + c + d

Area = ½(b₁ + b₂)h

Trapezoid

Circumference = 2πr

Area = πr²

Circle

Volume = lwh

Surface Area = 2lw + 2lh + 2wh

Rectangular Prism (Box)

Volume = s³

Surface Area = 6s²

Cube

Volume = πr²h

Surface Area = 2πrh + 2πr²

Cylinder

Volume = ⅓πr²h

Surface Area = πr√(r² + h²) + πr²

Cone

Volume = ⅓Bh

Square Pyramid

Volume = 4⁄3 πr³

Surface Area = 4πr²

Sphere

(3,4,5)	(5,12,13)
(7,24,25)	(8,15,17)
(9,40,41)	(11,60,61)
(12,35,37)

pythagorean triples

y – y1 = m(x – x1)

Point-Slope Form
