Quizplus · Accepted Answer

To convert the dimensions to meters (SI units), we use the conversion factors: 1 yard = 0.9144 meters, 1 foot = 0.3048 meters, and 1 inch = 0.0254 meters. Thus, the dimensions in meters are 1.5 yards = 1.5 * 0.9144 = 1.3716 meters, 1.2 feet = 1.2 * 0.3048 = 0.36576 meters, and 3.5 inches = 3.5 * 0.0254 = 0.0889 meters. The volume in cubic meters is 1.3716 * 0.36576 * 0.0889 ≈ 0.0445 cubic meters, which is 4.5 × 10^-2 m^3.
