How many cubic feet in 12 cubic meter (approximately)?

  • A.424
  • B.464
  • C.536
  • D.572

Answer: A

12 cubic metres is about 424 cubic feet.

One metre is 3.2808 feet, so one cubic metre is

\[ \begin{aligned} 3.2808^{3} &\approx 35.31\ \text{ft}^{3} \\ 12 \times 35.31 &\approx 423.8\ \text{ft}^{3} \end{aligned} \]

which rounds to 424. 464 and higher would need about 38.7 cubic feet per cubic metre or more, overstating the conversion; multiplying by 3.28 only once, as for a length, would give just 39.4.
