What is the volume in m³ of a cubic tank if the edge is x+3 m​

V = x³ + 9x² + 27x + 27

Step-by-step explanation:

The volume (V) of the tank is calculated as

aV = s³ ( s is the side length )

V = (x + 3)³

   = (x + 3)(x + 3)(x + 3) ← expand 2nd/3rd factors using FOIL

   = (x + 3)(x² + 6x + 9) ← distribute

   = x³ + 6x² + 9x + 3x² + 18x + 27 ← collect like terms

   = x³ + 9x² + 27x + 27

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
