Final answer:
To find the height of the garage, use the formula for the volume of a rectangular prism and solve for the height.
Step-by-step explanation:
To find the height of the garage, we can use the formula for the volume of a rectangular prism, which is V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
Given that the volume is 990m³, the length is 22m, and the width is 6m, we can plug in these values into the formula:
990 = 22 * 6 * h
To solve for h, divide both sides of the equation by (22 * 6):
h = 990 / (22 * 6)
h ≈ 7.5m
Therefore, the height of the garage is approximately 7.5 meters.
