Measure the length, width and height of the square or rectangle prism or object in inches. Record each of these on paper. Multiply the

**three**measurements together to find the**volume**using either paper and pencil or a calculator. This is the equation:**Volume**= length x width x height.

Similarly, how do you find the volume of a 3d polygon?

**3D** shapes have **volume**: the amount of cubic space inside of them. To **find volume**, you basically need the three dimensions: length, width, and height. For prisms, the formulas are derived by taking the area of the shape at the end, and multiplying that times the figure's height.

**Volume**of Rectangle-Based Solids Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for

**volume**is length × width × height. How you refer to the

**different**dimensions does not change the calculation: you may, for example, use 'depth' instead of 'height'.

Besides, what is the formula of volume?

Calculating **Volume** The **formula** to find the **volume** multiplies the length by the width by the height. The good news for a cube is that the measure of each of these dimensions is exactly the same. Therefore, you can multiply the length of any side three times. This results in the **formula**: **Volume** = side * side * side.

Area of Plane Shapes

Triangle Area = ½ × b × h b = base h = vertical height | Square Area = a^{2} a = length of side |
---|---|

Rectangle Area = w × h w = width h = height | Parallelogram Area = b × h b = base h = vertical height |
