How many cubic feet of dirt is in it?

You might be confused and are wondering why the correct answer here is 0. Since this question is under the IQ test, that is clearly a hint that it does not mean that the logical and mathematical answer is the answer. In solving for the cubic feet, multiply the width, length, and depth.

A yard is equal to 3 ft so, to solve for the correct answer multiply all dimensions to 3 or after getting the product, multiply it by 27. You will get an answer of 162 which is not in the choices. 0 is the right answer because the question asks for the cubic feet of dirt where John dug thus there is no dirt present in that hole.
