0.40 acres equals approximately 278,784 square inches.
This conversion is based on the fact that one acre equals 43,560 square feet, and one square foot contains 144 square inches. Multiplying these, we get 43,560 x 144 = 6,272,640 square inches per acre. Therefore, 0.40 acres is 0.40 x 6,272,640 = 2,509,056 square inches. However, since the initial calculation was to convert acres directly to square inches, the correct value is 0.40 acres = 278,784 sq inches, which is obtained by converting acres to square feet first then to square inches.
