Tap to reveal answer
Assume Statement 1 alone. Each edge of the cube has length between 160 centimeters and 180 centimeters; since one meter is equal to 100 centimeters, the length of one edge falls between 1.6 meters and 1.8 meters. Its volume therefore falls between
cubic meters
and
cubic meters.
The only whole number of meters that falls between these boundaries is 5 meters, so the question is answered.
Assume Statement 2 alone. The minimum surface area of the cube is 1,350 square decimeters, so, to find the minumum length of an edge, use the surface area formula, setting 
:
decimeters; divide by 10 (decimeters per meter) to convert to 1.5 meters.
Similarly, to get the maximum edge length, set 
:
decimeters; divide by 10 to get 1.8 meters.
The volume of the cube therefore falls between
cubic meters
and
cubic meters.
This leaves us with two possible whole number answers, 4 and 5, so the question is not answered.

A really backward country does not use inches, feet, yards, or meters to measure distance, it uses units called wumps and zumps. These units can also be used to form units of area and volume (i.e. square wumps, cubic zumps).
How many wumps are in one zump?
Statement 1: There are 361 square wumps in one square zump.

If there are 
wumps in a zump, then there are 
square wump in a square zump, and 
cubic wump in a cubic zump. Therefore, given the first statement, you can take the square root of the conversion factor to get the number of wumps in a zump; given the second, you can take the cube root of that conversion factor to the same end. In both cases you get 19.

If twenty inches are removed, the rod will have length inches, which is equal to yards.
Both lengths satisfy the conditions given in both statements, so, together, the statements provide insufficient information.
Assume both statements to be true. Examine these two scenarios.
Case 1: The metal rod is 56 inches long.
If four inches are removed from each end - that is, if eight inches total are removed - the rod will have length
If twenty inches are removed, the rod will have length
Case 2: The metal rod is 92 inches long.
If four inches are removed from each end - that is, if eight inches total are removed - the rod will have length
If twenty inches are removed, the rod will have length
Both lengths satisfy the conditions given in both statements, so, together, the statements provide insufficient information.

You are given a square metal sheet whose area can be given by a whole number of square feet. What is the length of each side?
Statement 1: The area of the sheet is between 3 square yards and 4 square yards inclusive.
Statement 2: Each side of the sheet measures between 60 and 72 inches inclusive.

Examine Statement 1. One yard comprises three feet, so one square yard comprises nine square feet. Three square yards is equal to square feet, and four square yards is equal to square feet. Therefore, the area in feet is one of the whole numbers .
Examine Statement 2. 60 inches is equal to feet, and 72 inches is equal to square feet. The range of areas of the square sheet can be found as follows:
Therefore, the area in feet is one of the whole numbers .
Therefore, the two statements together yield ten possible answers - the whole numbers from 27 to 36.
Examine Statement 1. One yard comprises three feet, so one square yard comprises nine square feet. Three square yards is equal to
Examine Statement 2. 60 inches is equal to
Therefore, the area in feet is one of the whole numbers

Assume Statement 1 alone.
24 inches is equal to feet, and 32 inches is equal to feet. If, as given in Statement 1, the length of each side of a square falls between these measures, the range of the area is as follows:
This gives us four possible whole numbers of square feet for the area - 4, 5, 6, and 7.
Assume Statement 2 alone. One yard comprises three feet, so one square yard comprises nine square feet. One half of a square yard is equal to half of nine, or four and a half, square feet. This allows us to narrow down the area to four whole numbers of square feet - 1, 2, 3, or 4.
Neither statement alone is sufficient, but both are - since 4 square feet is the only possibility that satisfies both statements, it can be found to be the answer to the question if both are assumed.
