The vol. of a cube of side length s is V=s^3.
So, if the side length is 5a+4b, then the volume of the cube is
V(a, b) = (5a+4b)^3. This could, of course, be expanded, using the binomial theorem, but there's no point in doing so.
Find the area of the base of the pyramid, then find the area of each side then add the areas. hope this help :)
To find the volume of the computer, we just have to multiply each coordinate.

<h2>Hence, the volume is 32.4 cubic inches.</h2>
