The correct answer is a 10
Vol (pyr) = 1/3 b × h, where h = 15 and b = base = area of triangular base = 1/2 b×h, where h = 12 and b = 13
V = 1/3 (1/2×12×13)×15
V = (1/3×1/2×12)×13×15
V = 2×13×15 = 30×13 = 390 in^3
This is a great place to apply the Pyth. Theorem. Let the width be W.
Then W^2 + 28^2 = 35^2.
Solving this, we get W^2 = 441. Taking the positive square root, we get
W = 21 ft
