Answer:
300 cubic inches
Step-by-step explanation:
To find the total volume when combining A and B, you simply need to add the volumes together.
Given:
Volume of A = 50 cubic inches
Volume of B = 250 cubic inches
Total Volume = Volume of A + Volume of B
Total Volume = 50 cubic inches + 250 cubic inches
Total Volume = 300 cubic inches
Therefore, the total volume when combining A and B is 300 cubic inches.
