Topics in Surface Areas and Volumes

1

Surface Area of Combination of Solids

  • When two solids are joined, some surfaces become internal and are not counted in total surface area
  • Total Surface Area = Sum of curved surface areas of all visible parts
  • Common combinations: Cylinder with hemispheres, Cone with hemisphere, Cuboid with hemisphere
2

Volume of Combination of Solids

  • Volume of combination = Sum of volumes of individual solids
  • Unlike surface area, no part of volume is lost when joining solids
  • Use standard volume formulas for each component
3

Problem Solving Strategies

  • Step 1: Identify the basic solids in the combination
  • Step 2: Determine what is required (surface area or volume)
  • Step 3: For surface area, identify visible surfaces only
