Any three-dimensional figure can be filled completely with congruent cubes and parts of cubes. The volume of a three-dimensional figure is the number of cubes it can hold. Each cube represents a unit of measure called a cubic unit.

4 cm · 3 cm · 1cm = 12 cm 3 length · width · height = volume area of base · height = volume 1 cm 4 cm 3 cm To find the volume of a rectangular prism, you can count cubes or multiply the lengths of the edges.

Find the volume of the figure. Additional Example 1A: Using a Formula to Find the Volume of a Prism V = Bh The volume of the prism is 192 ft 3. Use the formula. The base is a square: B = 4  4 = 16. V = 16  12 Substitute for B and h. Multiply.V = 192

Find the volume of the figure. Check It Out: Example 1A V = Bh The volume of the prism is 72 in 3. Use the formula. The base is a square: B = 3  3 = 9. V = 9  8 Substitute for B and h. Multiply.V = 72

Any unit of measurement with an exponent of 3 is a cubic unit. For example, cm 3 means “cubic centimeter” and in 3 means “cubic inch.” Reading Math
