Answer:

Explanation:

Compute the volumes of both the prism and the sphere. The difference of those volumes will give you the volume of the resulting composite figure.

Volume of prism = length * width * height = 8 * 12 * 6 = 576 cu inches

Volume of sphers = 4/3 * PI * r*3, where r = 1/2 diameter = 1 inches = 4/3 * 3.14159 * 1 = 4.188 cu inches ~ 4 cu inches

volume of composite figurre = 576 - 4 = 572 cu inches
