Match Multiple Fields In A Row Over Many Rows

I have 4 colums of customer input data, Length, Width, Height and Quantity. There are over 20 rows to accomodate multiple combinations. I have several other hidden pricing pages with all possible combinations including materials, pricing etc. Assuming I am on the frst pricing page and first combination I need a formula that will match the first 3 inputs per row and if true give me the 4rth input for the matching row.

Example:
Customer input-
row 1 = 8 - 12 - 4 - 15
row 2 = 4 - 4 - 2 - 25
etc.

Order Page-
Combination 1 = 4x4x2 quantity___ (input row 2 matches 4-4-2 give quantity 25)
Combination 2 = 4x8x2 quantity___ (no input row matches 4-8-2 give quantity 0)

Combination 36 = 8x12x4 quantity___ (input row 1 matches 8-12-4 give quantity 15)
