C) is the correct answer because since the base is 2 times the height, this means that the base is larger than the height. And when u look at c, and u add up all the sides( 10+10+20+20) you get the perimeter, 60 cm
only side 5 and 6 are greater than four and with fair rolls you would expect the die to land on each side once. So 2/6 times you would expect a roll greater than 4.
