Note: Finding the volume of a rectangular prism isn't so bad, especially if you already know the length, width, and height. Improve your math knowledge with free questions in "Volume of cubes and rectangular prisms" and thousands of other math skills. Calculate the area of a square or rectangle Recently: A couple realized not only that they fit together to 21 % but also what date they will break up, and why. The √ sign indicates square root of the entire bracket value. Two common methods for finding the volume of a solid of revolution are the disc method and the shell method of integration. Volume of a Rectangular Prism Worksheets, Geometry Worksheets for 4th grade, 5th grade and middle school Volume of a rectangle (V, cu ft) = (length, ft) x (width, ft) x (height, ft), then convert cubic feet to gallons (1 cubic foot = 7.48 gallons) If you have a rectangular shaped storage tank there is a very simple calculation that can give you the number of cubic feet that will fit inside of that rectangle.
Finding the volume. Calculate the area of a square or a rectangle using numerous different inputs in terms of dimensions. Other values have the same names as mentioned in the first formula. In this tutorial, you'll see how to use that information and the formula for the volume of a rectangular prism to get the answer.

Volume (V) = L x (P+Q) x √(4S 2 + 2PQ – Q 2 – P 2)/4 —- (equation 2) where S – Slant height. Volume (v) = Side (A) * Side (B) * Length (l) The rectangle bar has equal length sides with length, So we first calculate the volume of rectangle bar using below formula. Go through the following examples to understand how the volume of a trapezoidal prism is calculated.
