Answer:
Part A: the second choice
Part B: 72 blocks
Explanation:
The prism has 3 layers and 24 blocks per layer. The base of each layer of the second choice has a width of 8 and length of 3.
8*3=24.
Multiply the 24 blocks on each layer with the 3 layers and we get 72 blocks in total.
We can check this by multiplying the dimensions of the prism together. 3*3*8=72 and this verifies that we are correct.
