hi,

1 millimeter = 0.1 centimeter..
so 10 mm= 1 cm..
 10mm*10mm*10mm=1cm*1cm*1cm ..
 1000cu mm= 1 cu cm.. 
so 1 cu mm =  \frac{1}{1000}  cu cm..
 32490  cu mm = \frac{32490}{1000}  cu cm =  32.49  cu cm

ScottTargetTestPrep · Answer

Since 1 millimeter = 0.1 centimeter, then 1 millimeter^3 = 0.1 x 0.1 x 0.1 centimeter = 0.001 centimeter^3

Thus, 32,490 cubic millimeters = 32,490 x 0.001 = 32.49 cubic centimeters

Answer: C

ENGRTOMBA2018 · Answer

This is not a 700 level question. I have changed the tag to sub-600 level and added the complete source information.

As for this question, remember that 1 cm = 10 mm

Thus,  32490 {mm}^3 = 32490 * 10^{-3} {cm}^3 = 32.49 {cm}^3.

C is thus the correct answer.

Hope this helps.

Anonamy · Answer

Apologies, I intended to categorize it as 600 level. This question is #126 out of 175 in OG Quant 2016.

hi there

is my approach correct ? 1 cm = 10 mm 10 cm = 100 mm 100 cm = 1000 mm hence: 32,490 / 1000 = 32.49

Abhishek009 · Answer

1   millimeter  =  \frac{1}{10}   centimeter

So,  1   millimeter ^3  =  (\frac{1}{10})^3   centimeter^3

So, 32,490 cubic millimeters =  \frac{32,490}{1000}   centimeter^3

Answer must be (C) 32.49

hsn81960 · Answer

1mm=0.1CM9
10mm=1cm
so 10000mm= 1000cm
32490/1000= 32.49

StudiosTom · Answer

Simply since unit given is mm cubed and we want cm cubed, also conversion is given
Using basic unit conversion concept, multiple by conversion factor per unit exponent,I.e. 32490*01.*0.1*0.1= Ans
Ans- C

Omg.. the simple mistake you can make when you get comfortable and not read the units thoroughly

Basshead · Answer

1 centimeter = 10 millimeter

10 mm * 10 mm * 10 mm = 1 cm * 1 cm * 1 cm

1000 mm^3 = 1 cm^3 
 1 mm^3 = \frac{1}{1000} cm^3 
 \frac{32,490}{1000} = 32.49 cm^3

MHIKER · Answer

1 millimeter = 0.1 centimeter

1 cubic millimeter  = 0.1*0.1*0.1=0.001  cubic centimeter

The volume of the ball in cubic centimeter  = 32,490*0.001 = 32.49

The answer is C

CrackverbalGMAT · Answer

CONCEPT: Units & Conversion 1mm =0.1 cm SOLUTION: =>1mm3 = (0.1)^3 cm3 =>32490 mm3= 32490*(0.001) cm3 =32.49 cm3 (C) Hope this helps.

Keep studying.

sahuanamika · Answer

Now 1 mm = 0.1 cm

Volume = 32490 mm3
 = (0.1)^3*32490
 = 32490/1000
 = 32.49 cm3

Option C
