Nope, 8ft is equal to 96 inches.
Answer:
5
Step-by-step explanation:
Cause you can actually get multiple different answeres which you can make a statistical question on
Well, 15% of 60 is 9 so now you have to create a model :)
Refer to the attached image. Since one vertex is the origin and the other two lay on the coordinate axes, the triangle is a right triangle. This means that, if we consider AB to the be base, AC is his height, and vice versa.
Anyway, it means that the area is given by

Since AB is a horizontal segment and AC is a vertical segment, their length is given by the absolute difference of the non-constant coordinate: points A and B share the same x coordinate, so we subtract the y coordinates:

The opposite goes for AC: points A and C share the same y coordinate, so we subtract the x coordinates:

So, the area is

The volume will increase as each layer is added because you are adding more to that certain shape
