Finding the volume of this will mean that we'll have to know the formula. The formula for finding the volume of a prism is L x W x H.
L- Lenght
W - Width
H - Height.
So Volume is going to be equalled to 6 x 5 x 4 = 120 cm cubed

Answer:
Option B 3,-3,-6 is correct.
Step-by-step explanation:
We need to find real zeroes of 
Solving

Taking x^2 common from first 2 terms and -9 from last two terms we get

Taking (x+6) common

x^2-9 can be solved using formula a^2-b^2 = (a+b)(a-b)

Putting it equal to zero,

So, Option B 3,-3,-6 is correct.
