Answer:
V= 2* L*B*H
Explanation:
Although we are not given the dimension of the rectangular prisms in this question
The volume of a rectangular prism is
V= L*B*H
Since the number of the prism is two
Hence the volume of the two prisms
V= 2* L*B*H
Therefore, when the plugin the dimensions of the prism into the expression above, you will get the volume of the two prisms combined
