Acube with a side length 4p is stacked on another cube with side length 2q^2 what is the total volume of the cubes factored form?

Volume of first cube is (4p)^3 = 64 p^3.

Volume of second cube is (2q^2)^3 = 8q^6.

The total volume of the 2 cubes is thus 64 p^3 + 8 q^6, or 8(8p^3 + q^6).

all it means is function 3

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
