Hi All,

This question has a great Number Property 'shortcut' built into it; when combined with the answer choices, you can avoid almost all of the 'math' in this question.

We're told that the dimensions of a rectangular room are 10 meters by 6 meters by 4 meters. We're asked for the volume of the room in cubic CENTIMETERS? (1 meter=100 centimeters).

Converting the dimensions from meters to centimeters is pretty straight-forward - we just have to multiply each number by 100:

10 meters by 6 meters by 4 meters becomes...

1000 cm by 600 cm by 400 cm

Notice that these three numbers include 7 zeroes. When we multiply them together, the correct answer MUST have at AT LEAST 7 zeroes. Looking at the answer choices, there's only one answer that fits:

You can, and that way is much easier in my opinion.

10 * 6 * 4 = 240 meters cubed

1 meter = 100 cm
1 meter squared = (100cm)^2 = 10000 cm sq.
1 meter cubed = (100cm)^3 = 1000000 cm cubed

So 240 meter cubed * 1000000 cm^3/1m^3 = answer E
