To find the volume of the rectangular piece of metal, we need to multiply its length, width, and height: Volume = length x width x height Convert the measurements to meters to get a consistent unit: 8.0 cm = 0.08 m 1.20 m = 1.20 m 15.0 mm = 0.015 m Now we can substitute these values into the equation: Volume = 0.08 m x 1.20 m x 0.015 m = 0.00144 m^3 To convert cubic meters to cubic centimeters (cm^3), we need to multiply by 1,000,000. So: Volume = 0.00144 m^3 x 1,000,000 cm^3/m^3 = 1440 cm^3 Therefore, the answer is C, 1400cm³, rounded to the correct number of significant figures.
