Question:suppose a cube 1cm long on each side were scaled up to a cube 10cm long on each edge. 6a) what would the volume be of the scaled up cube be ? 6b) what would be the total surface area of the scaled up cube 6c) what is the length of each side of a cube if the volume is 125 cm^3? ANSWER ALL QUESTIONS!!!!!

Uranium, an important component of both nuclear weapons and nuclear reactors, has two major isotopes—U-238, which has a half-life of approximately 4.5 billion years, and U-235, which has a half-life of approximately 700 million years. Both were present in equal amounts at the time of the creation of the Earth, 4.5 billion years ago. How many billion years after the creation of the Earth had the amount of radiation from uranium decayed to half the amount present at the time of the creation of the Earth? (Round your answer to the nearest hundredth of a billion years.)

K. Consider the following nuclear decay equation; the half-life of Carbon 14 is 5730 years. What is name given to the particle represented by How many neutrons does this isotope of Carbon have?
