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?
6.67 x 100mm
8.50 x 102mm
1.15 x 103mm
2.50 x 103mm
1.50 x 105mm
ব্যাখ্যা
Height = \(\frac{volume}{area}\)
= Height = \(\frac{10^3}{1.5 \times 10^2}\)
= 6.67mm
= Height = \(\frac{10^3}{1.5 \times 10^2}\)
= 6.67mm
