Second and 4th are your answers!
First, you’re going to want to multiple 11 by 10 by 22, this helps you find the volume of the large rectangle. Then, you’re going to multiple 7 by 4 by 10, this helps you find the volume of the small rectangle. Finally, add those two numbers together and you get the total volume. When calculating the volume of rectangles, remember that you are multiplying length by height by depth. Hope this helps!
