Need to make own equation then I'm pretty sure find derrivitive then use restrictions to find the max or something

3. Most of the components of an electronic device are made to fit into a single box-shaped block. The length of the block is three times its width and the total surface area of the block must be 320 cm2 (in order to dissipate the heat produced). Determine the dimensions of the block that will maximize its volume. The width of the block must be at least 2 cm, while the length of the block cannot exceed 24 cm (due to space restrictions). totat Suffered [T/ C 9] must be 320 cma y (height) V = LXh xw x (width) De 32 cm Length L
