A through-hole is drilled through a 4 inch long block with square cross-section (1 inch x 1 inch). The drill bit has a diameter of 3/8 inch. The entry angle is perpendicular to and centered on a 1 inch by 4 inch surface.

Find the volume of the block after the hole has been drilled. (Round answer to the nearest hundredth.)

This problem may lend itself to Excel: find volume of box, and find volume of cylinder, and subtract.
