This is the unknown dimension of length calculated from the volume, and two other known dimensions of length & width, length & height, or width & height. 2nd LengthĮnter the other known dimension which can be either the length, width or height of the rectangular shaped box, and select the relevant length measurement units.

1st LengthĮnter one of the known dimensions which can be either the length, width or height of the rectangular shaped box, and select the relevant length measurement units. In that case, you would use the formula: perimeter 2 × length plus 2 × width. If you dont have the area, you can use the rectangles perimeter instead. Just plug the area and length of the rectangle into the formula and solve for the width. The formula used by this calculator to calculate the unknown length, width or height of a rectangular shaped box is:Įnter the volume of the rectangular shaped box, and select the relevant volumetric units. To find the width of a rectangle, use the formula: area length × width.

Also a graphic of the rectangular box will be drawn and labels added for the volume and each dimension of length, along with the selected measurement units. That ratio means that the width is m n times the height, so you know that x m n y. Once the parameters have been entered for volume and the other two known length dimensions, the unknown length dimension will be calculated.

This online tool will calculate the length, width or height of a rectangular shaped box from the volume, and two other known dimensions of length. The area of a rectangle is the length times the width: (ALW).
