Answer:
Third and fourth statement are true ("There are 7 unit cubes..." and "The volume of the prism can be found by 12x3..."). The rest are untrue.
Step-by-step explanation:
No.Middle layer has (2+3) five cubes, not seven.
No. Bottom layer has (2+3+4) nine cubes, the middle layer has five and the top has two. In total, this is sixteen cubes, not nine.
Yes. You can see 9 cubes and there are 16 total, so yes, seven are hidden from view.
Yes. Volume can also be found by multiplying length by width by depth, which is 4x3x3=12x3=36.
No. The volume of the prism is 36. There are 16 cubes. 16 is not half of 36.
