My cousin asked me for help on a math question. I thought I figured it out but my answer seems too simple? Help? It's just algebra, polynomials and such. Each of the three dimensions of a cube with sides of length s centimeters is decreased by a whole number of centimeters. The new volume in cubic centimeters is given by V(s) = s^3 - 13s^s + 54s - 72 a.) Find V(10). This was easy, I just plugged 10 in for s and got 168 b.) If the new width is s-6 centimeters, then what are the new length and height? I figured they must be the same as the width since it's a cube, so s-6 c.) Find the volume when s = 10 by multiplying the length, width, and height. I figured plugging 10 in for s in respect to each side (s-6), so 4x4x4 is 64 Any help or confirmation is appreciated, from one nerd to another.
