A cube is a solid box whose every surface is a square of same area.
Take an empty box with open top in the shape of a cube whose each edge is 2 cm. Now fit cubes of edges 1 cm in it. From the figure it is clear that 8 such cubes will fit in it. So the volume of the box will be equal to the volume of 8 unit cubes together.
Firstly the equation would be y=7.7x+59 (A)The slope is 7.7 (B) and shows that there is a 7.7 charge per week the person attends. (A)The y intercept is 59 (B) and is the initial fee that the gym charges.
