Question 776778
Surface area of a cube = 6*x^2
Surface area of the larger cube is 6*4^2 = 96 cm^2
now the ratio of the smaller cube's surface area to the larger cube's surface area is 1/4, we can write
1/4 = surface area of smaller cube / 96
cross multiply the two fractions and we ge
surface area of smaller cube * 4 = 96
a)surface area of smaller cube = 24 cm^2
b)24 = 6*n^2
  4 = n^2
  n = 2 cm
