What is vlume of cube | vol=L x W x H s3 uints, cm, ft, in,cubic uints |

| memorize |

Vulme of tringel: vol = area x hight 1/2 B x H x hight

Vulme of clyinder: vol = area x hight = pir2 untis cm in cubic uints

Vlume of spera: 4/3 pir3

Surface area of a cube: s x a x 62

Surface are of regtul: SA 2A+ 213 + 2C 2(2 X 5) +2 =20+ 100+40=160uints

Surfac area of a trilge prism: SA=2C 1/2 BH

Pirmter of a tringel:p=s+5 + s3

Pirmetr of a qudnlateral: p=S1+S2+S3+S4

Pirmert of a rectengel:P=2L+2W =2B+2H

Piremter of a squrea:P=4S
