Answer:

1,176 cm²

  • Start the equation

[tex]V = b * l * h\\V = 18 * 6 * 12\\\\= 1,296[/tex]

  • Find volume of second composite figure

[tex]V = h * l + b * a[/tex]

Assume all sides are 10

[tex]V = 10 * 10 + 10 + 10\\\\= 120[/tex]

  • Finally, subtract both values

[tex]V = 1,296 - 120 = 1,176[/tex]
