A pyramid and a cube monument are being created for a display. Their volumes are supposed to be the same. The volume of a pyramid is ⅓ times the height times the base area (V=13hb). The pyramids height (h) and base area (b) are given: h=(3x+6) and b=x2+2x+1. The volume of the cube is V=x3+4x2+27. What value of x would make the volumes the same? What is the volume of the cube? SHOW WORK PLEASE!

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
