Answer:
1022
Explanation:
Let's find the volume of the cube at the top of the solid.
The formula is V = edge*3
7x7x7 = 343
Since there is two identical cubes (top and bottom), you multiply the product by 2.
343x2 = 686
Now, let's find the volume of the middle cube.
6x8x7 = 336
Finally, let's add it all together.
686+336 = 1022
The volume of the solid is 1022.
