What is the VOLUME of the composite figure below?

Answer:
216 in³
Step-by-step explanation:
We can split it into 3 prisms:
1. Horizontal one: 12×3×3
2 2 vertical ones: 6×3×3
Total volume: 12×3×3+2×6×3×3=3×3(12+12)=
9×24=216in³
Answer:
216 inch ^3 is the vol
Step-by-step explanation:
just act like it a full rectangle prism and find the volume of that then subtract the vol of the small parts we added.
So to find the vol it be 12 times 3 times 9 = 324 in
but we filled in those gaps so now we find the volume of those and subtract it.
Gap 1 would be 3 by 6 by 3 = 54 in but their two gaps that are the same so double it = 108 in
now take 324 - 108 =216 in
