Can someone please help me! Thank you in advance!

Volume: 825 cubic units

Step-by-step explanation:

You can find the area in 2 ways:

1. Find the volume and subtract

This method is done by finding the volume of a 5*20*10 prism (the 10 comes from the two 5s on the right), and then subtracting a 5*5*5 cube.

This method works because, as you can see from the diagram, a 5*5*5 cube was "taken out" of a corner

2. Find the volume and add.

This method is similar to the one above. The only difference is that you will use a 5*15*10 prism. Then, add the 5*5*5 cube.

3. Finding the volume

I am going to use the first equation, as the numbers are easier to work with.

5*20*10=1,000

5*5*5=125

1000-125= 875

I hope this helps! Feel free to ask any questions!
