A. using the image shown, determine the area of the shaped region._
B. applying surface area formula, SA=2lw+2lh+2wh determine the surface area of the image._
C. Applying the volume formula, V =lwh, determine the volume of the image._

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
