Answer:
290
Step-by-step explanation:
These are rectangular prisms. The volume formula for a rectangular prism is
l x w x h.
I'll call the bottom cuboid 'Figure A'.
Figure A has a length of 8, a width of 5, and a height of 5. The volume formula is: 8 x 5 x 5. 40 x 5 =200
The volume of Figure A is 200.
I'll call the top cuboid Figure B.
Figure B has a length of 3, a width of 5, and a height of 6. That turns into
3 x 5 x 6.
The volume of Figure B is 90.
The volume of a composite figure is the sum of the figure's volume.
200+90=290
