a container with uniform cross -sectional area of 160cm2 is filled with water to a certain level. If a metal cuboid of dimensions 10cm x 10cm x12 cm is placed inside the container and totally submerged in water, find the rise in the water level.

✔ 最佳答案
let the rise in water level be hthe change in total volumn = the volumn of metal cuboid = 10 x 10 x 12 = 1200cm3
uniform cross-sectional area x change in water level = change in volumn
160cm2 x h = 1200cm3
therefore h = 7.5cm
hope it's gonna help~

The volume of the metal cuboid = 10 x 10 x 12 = 1200 cm3
Let n be the rise in the water level
160 n = 1200
n = 7.5
Therefore, the rise in the water level is 7.5 cm.

volumn
Let n be the rise in the water level
160 n = 1200
n = 7.5
Therefore, the rise in the water level is 7.5 cm.
