Step one, we have two shapes here we need to figure out the volume of the smaller rectangle. so we have the width of 6 the height of 2 and now we need to find the length of the smaller rectangle. To do so it is the same length as the other rectangle so we will replace the missing length with 13 cm since that is what its length is. Now we multiply 6x2x13=156cm
Step two now we find the Volume of the bigger rectangle. Since we have all of the sides, this part will be easy peasy. Multiply 5x13x22 to get 1430.
Final step is add the two volumes together to get the total volume of this shape. Which is 1586 cm^2
