Precalculus
K(x) = x^2(x^2 + 16), where K(x) = x^2. I got K(x^2) = x^8 + 16x^4. Is this right? Thanks :))

The formula for density is p = m/v, where p is density, m is mass, and v is volume. First, you would figure out the volume by: V = 3 cm * 3 cm * 3 cm V = 27 cubic centimeters Plug everything that you know into the formula: p = 27g / 27cm^3 p = ? g/cm^3 Hope this helps! :)
