Answer:
the 8×3×11 one
Step-by-step explanation:
we need to find the surface area of each.

for the 10×10×3=
2(10×3+10×10+10×3)
2(30+100+60)
2(190)
380
for the 8×3×11
2(8×3+11×8+11×3)
2(24+88+33)
2(145)
290
Answer: None of them are functions.
Step-by-step explanation:
By definition, a relation is a function if and only if each input value have an unique output value.
You need to remember that the input values are the x-values and the output values are the y-values.
In the first table you can observe that the input value 2 has two different output values:

Therefore, this relation is not a function.
Notice that in the second table the input value -4 has two different output values:

Therefore, this relation is not a function.
In the set
, observe that the input value -5 has two different output values:

Therefore, this relation is not a function.
