Two-way lookup with INDEX and MATCH

Summary
To lookup in value in a table using both rows and columns, you can build a formula that does a two-way lookup with INDEX and MATCH. In the example shown, the formula in J8 is:
Note: this formula is set to "approximate match", so row values and column values must be sorted.
Explanation
The core of this formula is INDEX, which is simply retrieving a value from C6:G10 (the "data") based on a row number and a column number.
=INDEX(C6:G10, row, column)
To get the row and column numbers, we use MATCH, configured for approximate match, by setting the 3rd argument to 1 (TRUE):
In the example, MATCH will return 2 when width is 290, and 3 when height is 300.
In the end, the formula reduces to:
=INDEX(C6:G10, 2, 3) = 1800
