All the options are correct.
If we look at the formula of prismoidal, we can see that it contains, three areas = area of faces at top and bottom and area of midway section
Thus it can be used to calculate the a) calculate surface area for cylindrical rings And b) estimate the surface area of edged non-prismoidal solids.
In the volume formula of prismoidal, the factor (depth/6) is multiplied by the three areas as mentioned above, this gives the volume of faces at top and bottom and midway section. Thus option C and D are also correct.

The real question is...can a box match?
Answer:
Option (4)
Explanation:
The radiation are defined as the energy that is liberated from atoms in the form of electromagnetic waves or minute particles of matter. For example, the radiations that are emitted from the sun in the form of light.
This radiations are mainly of 3 types. This includes-
(a) Alpha Radiation- These are the short ranged particles and are very heavy. This radiations cannot penetrate the human skins but they can cause harmful diseases.
(b) Beta Radiation- These are also the short-ranged particles but they lighter. This radiations can penetrate the human skin upto the depth where the new skins are created.
(c) Gamma Radiation- These are highly dangerous and are penetrable to the human skin. This type of radiations are often used for the medical purposes.
Thus, the correct answer is option (4).
