consider the figure composed of two rectangular prisms

The first one - 2 height lenght 6
The sceond one- 4 by 8 by 10 by 2

To find the total volume of the figure composed of two rectangular prisms, we need to calculate the volume of each prism and then add them together.

First prism:
Volume = length x width x height
Volume = 6 x 6 x 2
Volume = 72 cubic units

Second prism:
Volume = length x width x height
Volume = 4 x 8 x 10
Volume = 320 cubic units

Total volume of the figure = 72 + 320
Total volume = 392 cubic units

Therefore, the total volume of the figure composed of two rectangular prisms is 392 cubic units.
