Answer:
V = 11 times 9 times 7
Step-by-step explanation:
To answer this question, a dimensional analysis must be done.
The volume has cube length as a unit, that is, l ^ 3
We analyze each option
V = base * height * height
ignoring what each one means, we know that each one is measured in length therefore:
V = L * L * L = L ^ 3 that is to say that in this way the volume can be found.
The other way is:
V = base + height + height
If we replace, we have to:
V = L + L + L = L, and the volume does not have units of length, therefore this option is not viable.
Which means that the option of V = 11 times 9 times 7 is correct.
I must mention, that the true way to calculate the volume in this case would be:
V = Base area * height
V = (base + height / 2) * height
