Answer 4

@Mokeira do you have a FORMULA OR SOMETHING SRRY caps on

Answer 5

The volume of that shape can be split up into a rectangular solid and a cube.

Add the two smaller volumes together will get you the volume of the entire unit.

ignoring a = 2 for now ...

Volume of the rectangular solid is:

V = a(a)(2a)
V = 2a³

volume of the cube is:

V = a³

Add them together:

2a³ + a³
3a³

Now we can put a = 2 in there and simplify:

3(2)³
3(8)
24

Answer 6

try it like how we did for surface area...take them as Figure A and B
find volume for each then add up to get total volume
