Answer:
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!
