One student multiplies the edge lengths of a right rectangular prism to get the a volume of 78 cubic units. What is one way to check that the volume is correct?(1 point)

Multiply the edge length of one cube.

Count the number of 18-inch cubes that will fit inside the prism.

Use the formula method to see if the volume is the same.

To check if the volume calculated is correct for a right rectangular prism, you can use the formula method to see if the volume calculated matches the given volume of 78 cubic units. The formula for the volume of a right rectangular prism is V = l × w × h, where V represents volume, l represents length, w represents width, and h represents height.

To perform the check:

1. Identify the length, width, and height of the right rectangular prism.
2. Multiply the length, width, and height together using the formula V = l × w × h.
3. Compare the result obtained from the calculation with the given volume of 78 cubic units.
4. If the calculated volume matches the given volume, then the multiplication was correct.

Therefore, using the formula method is one way to check if the volume calculated for the right rectangular prism is correct.
