Price of Resin compared to Filament?

[Compro01]

A solid 6" cube would have a volume of 3.54 litres.

For resin :

Makerjuice SubG+ is $45/litre, and the 3.5% shrinkage will require you to print 3.67 litres of resin, so you'd need $165.15 worth to print it.

Makerjuice SubG, which is $40/litre, and the 8% shrinkage will require you to print 3.85 litres of resin, brings the cost down to $154.00.

Formlabs resin is $149/litre, which brings the cost to $527.46. Price will probably be higher than that due to shrinkage, but Formlabs doesn't seem to specify the resin shrinkage anywhere I can find.

For filament :

A 1kg spool of 1.75mm PLA is about 330m long, giving a volume of about 800ml, so you'd need 4.4 spools. Makerbot sells it for $48/spool (ordinary solid colour), so that's $211.20 worth of filament.

A 1kg spool of 1.75mm ABS filament would be about 400m long, giving a volume of 962ml, so you'd need 3.68 spools. Makerbot sells it for $48/spool also, so that's $176.63.

Pushplastic sells both PLA and ABS for $19/kg, which would cut the costs to $83.60 and $69.91, respectively.
