Question 275735
V(s)= s^3  13s^2 + 54s  72. 
(a) Find V(10). 
To find V(10), replace s with 10 in your function and simplify. Here is the set up: 
V(10) = (10)^3 - 13(10^2) + 54(10) - 72 
Can you do it now? 

(b) If the new width is (s  6) centimeters, then what are the
new length and height? 
The volume of a cube is usually found using V = L*W*H = side^3 
If the width is (s - 6), what do you think the new width could be? 

(c) Find the volume when s = 10 by multiplying the
length, width, and height. 
Look at part (a) of this question for your hint to part (c). 
Understand?
