Suppose the lateral area of a right rectangular prism is 144 square centimeters. If the length is three times the width and the height is twice the width, find the surface area.

The cross section of a solid is an octagon. Name the solids that have octagonal cross sections.

Lucita needs to figure out how much it will cost to repaint the walls in her bedroom. She knows the cost of paint per gallon \(g,\) how many square feet a gallon will cover \(f,\) and the length \(\ell\) width \(w,\) and height \(h\) of her room. Which formula should Lucita use to calculate the total cost \(c\) of painting her room? A \(g=\frac{w \ell h+c}{f}\) \(\mathbf{B} \quad c=\frac{(w h+\ell h)}{f} \cdot g\) \(\mathbf{C} c=\frac{2(w h+\ell h)}{f} \cdot g\) \(\mathbf{D} c=\frac{2(w h+\ell h+\ell w)}{g} \cdot f\)
