B Correct answer
Explanation

Volume = length * breadth * height. Given V = 1.92, breadth = 1.2, height = 0.8 (80 cm). 1.92 = length * 1.2 * 0.8. 1.92 = length * 0.96. Length = 1.92 / 0.96 = 2.

AI explanation

First, convert the height into meters to match the volume unit, making the height 0.80 m. Using the volume of a cuboid formula, Volume = length * breadth * height, we set up the equation 1.92 = length * 1.20 * 0.80. This simplifies to 1.92 = length * 0.96, so the length is 1.92 / 0.96 = 2 m. The length is 2 m.
