  1. Volume Any solid figure can be filled completely with congruent cubes and parts of cubes. The volumeof a solid is the number of cubes it can hold. Each cube represents a unit of measure called a cubic unit.

  2. Prisms:

  3. 1 cm 3 cm 4 cm Visual Aid: 4 cm · 3 cm · 1cm = 12 cm3 length · width · height = volume area of base · height = volume

  4. Examples: 4.1 ft 4.1 ft 12 ft V = Bh Use the formula. The bases are rectangles. The area of each rectangular base is 12 · 4.1 = 49.2 V = 49.2· 4.1 Substitute for B and h. Multiply. V = 201.72 The volume to the nearest tenth is 201.7 ft3.

  5. On your own… 1.) 861.8 cm3 2.) triangular prism: base area = 24 ft2, height = 13 ft 312 ft3
