Given the biconditional logic for hexagon, it can be defined that a hexagon is a polygon with six sides. For information, a biconditional statement <span>is true if both parts have the same truth value. For example, a condition x is true if and only if condition y is also true.</span>
Use similar volume to calculate which is the (ratio of edges)^3 = (ration of volume) so just put the numbers in, let the volume of smaller pyramid be y. (3/4)^3 = y/320 27/64 = y/320 y=135in3
