A Bulk Food Storage Bin with Dimensions 3 Feet by 4

A bulk food storage bin with dimensions 3 feet by 4 feet by 5 feet needs to be increased in size to hold five times as much food as the current bin.(Assume each dimension is increased by the same amount. ) .Write a function that represents the volume of the new bin. ​

A) ​V(x) = x³ + 12x² + 47x + 60 = -300
B) V(x) = x³ + 12x² + 47x + 60 = 300
C) V(x) = x³ + 12x² + 47x = 300
D) V(x) = x³ + 12x² - 47x - 60 = 300
E) V(x) = x³ - 12x² + 47x - 60 = 300
