The correct answer is 25.12 cubic meters.
To find the volume of the sandcastle mold, we need to use the formula for the volume of a cone: V = (1/3)πr^2h, where r is the radius and h is the height.
In this case, the diameter is given as 4 meters, so the radius (r) would be half of that, which is 2 meters.
Plugging these values into the formula, we get: V = (1/3) * 3.14 * 2^2 * 6 = 25.12 cubic meters.
