Answer:1 foot
If 3 units equal 3 feet, what is the value of 1 unit?
Answer:
Assuming you mean on a number line.
So because it says NOT a way....I think it's A...Maybe I'm wrong but whatever.
I don't have a clue what this a0 at the right stands for, but if we neglected it, we can solve the problem.

So the answer would be 25.
Hope this helps.
slated surface
17 × 20 = 340
2 triangle sides
2 × 8 × 15 ÷ 2 = 120
backside
8 × 20 = 160
bottom
15 × 20 = 300
sum all of it
340 + 120 + 160 + 300 = 920
