Well, surface area isn't changing, just the units. So it can't be A and B. There are 100 cm in one metre. And 10,000 cm^2 in a square metre. So you must have a larger number if you make it cm.

OpenStudy (matthew120):

so c ?

No.

OpenStudy (matthew120):

then d

OpenStudy (matthew120):

because If we know that 1 meter = 100 centimeters then we have to know that multiplying by 100 will increase the number. The surface will stay the same, but it will increase when converted to square centimeters.
