Each cube is 128/2 = 64 cm3
x * x * x = 64
x^3 = 64 x = 4 cm side length
l x w = area
4/(4+3) = 4/7 4/7 x = l
3/(4+3) = 3/7 3/7 x = w
4/7 x * 3/7 x = 588
12 /49 x^2 = 588

interest per quarter in decimal form = .05/4

x = total voters = 1400/ .28 =..............
100% - 18% = 82 % = 'the remaining calls'
82 * .08 = 6.56% of calls makes a sale
