Surface Area And Volume Of Shapes

Surface Area And Volume Of Shapes

1. 3D Shapes

   • Surface Area and Volume always use 3D Shapes. They never use 2D Shapes

2. Volume

   • The Units are always Cubed
   • When working out the volume times all the numbers together
     • Example H:3 W:4 L:5
       • 3x4x5 = 60cm3

3. Surface Area

   • The Units when working out surface area are always squared
   • When Working out the Surface Area times 2 number together but make sure each nuber is multiplied by every number
     • On most occasins you may have to multiply it by 2
       • You will find this out if there are two sides of the same hight, length and width
         • After all numbers are multiplied add them all together to get the Surface Area
     • Example H:3 W:4 L:5
       • 3x5x2
         • 30cm2
           • 30=
             • 94cm2
               • This is the surface area of this shape!
       • 3x4x2
         • 24cm2
           • 24+
       • 5x4x2
         • 40cm2
           • 40+
