Answer:
B. He added 3.5 and 5 when he should have multiplied them.
Step-by-step explanation:
Let's observe Joe's steps:
- V = lwh
- 204 = 3.5 * (5) * l
Here, * means to multiply, so we're supposed to multiply 3.5 to 5, which would give you the answer 17.5. Unfortunately, look what Joe got: he obtained the value of 8.5, and if we observe, 3.5 + 5 = 8.5.
That's how we know that Joe added instead of multiplied, as he should have done. Thus, the answer is B.
ST = 1/2 (RV) = VQ = 6
answer
ST = 6
