Formula to find missing dimension for right rectangular prism

1 answer

The formula to find missing dimension for a right rectangular prism depends on which dimensions are given. Here are the formulas for finding each missing dimension:

- If the length (l) and width (w) are given and the height (h) is missing: h = V / (l * w), where V is the volume of the prism.
- If the length (l) and height (h) are given and the width (w) is missing: w = V / (l * h).
- If the width (w) and height (h) are given and the length (l) is missing: l = V / (w * h).
- If the volume (V) and two dimensions (l and w or l and h or w and h) are given and the third dimension is missing: the formula to use depends on which two dimensions are given, but it will always involve dividing the volume by the product of the two known dimensions.
