Answer:
26 is c, 20 is b, 30 is c
Step-by-step explanation:
26:
The relationship between 2,560 and 256 is that 2,560 is 10 times 256, and the only options that include "10 x" is b and c and b has (2+5+6) which doesn't equal 256, whereas c does.
20:
The bottom layer is 15 blocks, so then add the two more on top of the bottom layer and it's 17, so b.
30:
The width of the prism is 2, the length is 8, and the height is 4, so 2x8x4 is 64. They want a prism that's 1/4 the volume, so 64/4 is 16. (You could also just take 4 out of the 2x9x4 equation and get 2x8 which is 16).
