The volume of a prism whose base is a regular polygon.

To find the volume of a prism, multiply the area of the base by the heigth.


You can rotate the figure by moving the red dot. What you are going to measure has to be straight.

Move the ruler from its ends, one after the other.
Do measurements in centimetres, if the value is not a whole number, use a decimal number.
Write down each measurement in the box below and hit Enter. If it is correct, it will appear in the window.

Do the necessary calculations to find the perimeter of the base, the surface area of the base and the volume of the prism. Write it down in the corresponding boxes below.

Take  the corresponding units to each yellow circle.
