A 30 cm object might be a remote.
10 cm = 3.93700 "
a jumbo candle stick from target.
4 m / 10 cm = 400 cm / 10 cm = 40
2 x (24 + 10)...68cm
It is: 2*3*10 = 60 cubic cm
45 cm.
If an object at is 2.5 cm long is placed on the axis of a concave mirror that is 30 cm radius of curvature at a distance of 10 cm away from it, the position size and nature of the image formed would be 20 cm. This is a math problem.
The same object that is 11.5 cm long
Nothing
the density of an object that is 10 cm by 2 cm and has a mass 400g will be 10000 Kg m-3. This can be calculated by the formula, density = mass/volume
