2. Q: As a detective, you happen upon a murder scene. On a wall, you find a pentagram drawn in blood, with each side measuring 6 inches. The width of the brush is 0.5 inches wide. Assuming a 2 sq. inch area contains 1 mL of blood, how many millimeters of blood is used? Round to the nearest tenth (remember to count each intersection twice or thrice).
A: 13.3 mL.
