7.1 surface area and volume.
v=volume, s=surface,l= length, w=width, h=hight

v=bh, v=(6)(6)=36u^3 sections, 1surface area and volume,

To find the surface area or a cube. use this formula S=6s squared or V=s cubed

= = = = = = = = = = = = =7.2surface area and volume of prisms= -surface area of a rifgt prism ...

s=L+2B or S=hp+2B=

Cavallieri's principle -If two solids have equal heights and the cross sections formed by every plane parellel to the bases of both soilds and equal areas, then the two solids have equal volumes.

-volume of a prism- volume v, h height, B=base=Bh

=7.3surface area and volume of pyramids=

-surface area of a regular pyramid, surface areas, lateral areaL, baseB, perimeterp, slant hieght = l

-s=L+B or s=1/2lp+B-

-volume of a prymaid, volumev, heighth, base = B

-v=1/3Bh- -

=7.4 surface area and volume of a cylinders=

- surface area of a right cylinder, surface areav,lateral area of a cylinderL,base=B,raduis=r,height=h -S=L+2B or S=2pi rh+2 pi r2-

-volume of a cylinder, volumev, raduisr, height= h, base =B -v=Bh or v= pi r 2 h.-

=**7.5 surface area and volume of a cone**= . surface area of a right cone forumal.

surface areas, lateral area L, base B, raduis r, slant height l.

-S=L+B or S=pirl+pir^2-

volume of a cone forumal. V= voulume, raduis= r, height= h, base = B -v=1/3Bh or V=1/3 pi r^2h-
