A metal cube of volume 103mm3 is lowered into a measuring cylinder containing water. If the internal cross-sectional area of the cylinder is 1.5 x 102mm2, by how much does the water level rise in the cylinder?
-
A.
6.67 x 100mm -
B.
8.50 x 102mm -
C.
1.15 x 103mm -
D.
2.50 x 103mm -
E.
1.50 x 105mm
Correct Answer: Option A
Explanation
Height = (frac{volume}{area})
= Height = (frac{10^3}{1.5 times 10^2})
= 6.67mm
