A 30 cm object might be a remote.
30 feet = 914.4 cm
A standard ruler is typically 30 cm long. Additionally, a medium-sized kitchen knife or a typical cereal box can also measure around this length. These common household items can help visualize the length of 30 cm easily.

A small measures 15 cm .It is 15 cm long . It means 2 small ruler will be equal to 30 cm and 5 cm of 3rd ruler . It is 35 cm long .
30 cm = 11.8 inches, approx.
45 cm.
30 feet = 914.4 cm
The same object that is 11.5 cm long
30 what cm's? 30 cm is 300 mm
30 cm
The density of the object can be calculated using the formula: Density = Mass/Volume. Plugging in the values, Density = 30 grams / 10 cm^3 = 3 grams/cm^3. Therefore, the density of the object is 3 grams/cm^3.

30 cm exactly and 8 cm up
The mirror equation for concave mirrors is 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. Since the object distance is 10 cm from the mirror and the radius of curvature is 30 cm, the focal length (f) is half the radius of curvature, which is 15 cm. Substituting the values, you can find the image distance (di) which is -20 cm (negative indicates a real image). The magnification can be calculated using M = -di/do, which in this case is -20/-10 = 2. This means the image is inverted and magnified by a factor of 2, located at a distance of 20 cm on the same side as the object from the mirror.
