Final answer:
To measure the volume of a rectangular prism, use the formula V = length x width x height. Measure the length, width, and height of the prism using a ruler, and then multiply the measurements together to find the volume.
Step-by-step explanation:
When measuring the volume of a rectangular prism, you can use the formula V = length x width x height. First, measure the length, width, and height of the prism using a ruler. Then, multiply these three measurements together to get the volume of the prism. Make sure to use the same unit of measurement for all three dimensions.
