Answer:

720³ cm

The formula for volume is...

  • length ×
  • width ×
  • height

With that information, we should multiply the smaller numbers first.

[tex]B = \frac{1}{2} xy[/tex]

  • Replace the substituted parameters with 9 and 15, then multiply them and solve.

[tex]B = \frac{1}{2}(9)(15) = \frac{135}{2}[/tex]

  • UseV for volume.

[tex]V = \frac{1}{3} * \frac{135}{2} * 32 = 45 * 16[/tex]

  • Reducing the expression ↓

[tex]V = 720^3~cm[/tex]

Hence, the volume is 720³ cm
