Volume + SA

• $1cm^2=$$?\ mm^2$


  $\left(10\ x\ 10\ mm^2\right)=$$100mm^2$
• $1cm^3=$$?\ mm^3$


  $\left(10\ \times\ 10\ \times\ 10\ mm^3\right)=$$1000mm^3$
• $1m^2=$$?\ cm^2$


  $\left(100\times100\ cm^2\right)=$$10000cm^2$
• $1m^3=$$?\ cm^3$


  $\left(100\times100\times100cm^3\right)=$$1,000,000cm^3$
• 1 litre = $?\ cm^3$


  $1,000\ cm^3$
• Volume of a prism(any solid with parallel sides)

  Volume = cross-sectional area x height

  V = CSA x H

  (ANY SOLID WITH PARALLEL SIDES THAT HAS A CONSTANT CROSS-SECTION IS CALLED A PRISM)

  
• Volume of a cone

  $\frac{1}{3}\times\pi r^2\times h$

  
• Curved surface area of a cone

  Curved surface area = $\pi rl$

  (L = the slant height)
• Volume of a cuboid

  Volume of cuboid = width x depth x height
• Surface area of a cuboid (a prism with a rectangular cross section)

  Surface area = sum of the area of the si rectangles making up the face
• Volume of a cylinder

  Volume of a cylinder = $\pi r^2h$

  
• Curved surface area of a cylinder

  $2\pi rh$
• Volume of a sphere

  Volume of a sphere = $\frac{4}{3}\pi r^3$
• Surface area of a sphere

  $4\pi r^2$
