The formula for the volume of a cuboid is length x width x height. We know that the volume of the cuboid is 84 m³, the length is 7 m, and the width is 6 m.
Substituting the given values into the formula, we get:
7 m x 6 m x height = 84 m³
Simplifying the equation:
42 m² x height = 84 m³
height = 84 m³ / 42 m² = 2 m
Therefore, the height of the cuboid is 2 m.
