Excel is a powerful tool that can be used to create and manipulate 3D formulas. To create a 3D formula in Excel, you will need to use the SUMPRODUCT function, which allows you to sum the product of ranges or arrays.

Here is an example of a 3D formula using the SUMPRODUCT function:

=SUMPRODUCT(A1:C1,A2:C2,A3:C3)

This formula will calculate the sum of the product of the values in the range A1:C1, the values in the range A2:C2, and the values in the range A3:C3.

You can also use the SUMPRODUCT function to create more complex 3D formulas by adding additional ranges or arrays as arguments.

For example:

=SUMPRODUCT(A1:C1,A2:C2,A3:C3,D1:F1,D2:F2,D3:F3)

This formula will calculate the sum of the product of the values in the ranges A1:C1, A2:C2, A3:C3, D1:F1, D2:F2, and D3:F3.

I hope this helps! Let me know if you have any other questions.
