I'll assume you meant: "how many cubic inches are in 1.8 cubic feet?" since cubic feet are a measure of volume whereas inches are a measure of length:
1 ft = 12 in
⇒ 1 cu ft = 1 ft x 1 ft x 1 ft
= 12 in x 12 in x 12 in
= 1728 cu in
⇒ 1.8 cu ft = 1.8 x 1728 cu in
= 3110.4 cu in
That is 3110.4 cubic inches.
