This is a notable trinomial.
You have to find two numbers which summed give 1 and multiplied give 20.
In this case +4 and -5
-5+4 = -1(a)
-5*4 = -20
So (a+4)(a-5)

Answer:
s = ∛( 1953.125 cm³ ) = 12.5 cm
Step-by-step explanation:
The volume of a cube is V = s³, where s represents the length of one edge.
Here, V = s³ = 1953.125 cm³, and we need to solve for s. Do this by taking the cube root of both sides:
s = ∛( 1953.125 cm³ ) = 12.5 cm
