What is the volume of a cube if the length, width, and height are 1ft? a)6 cubic feet
b)3 cubic feet
c)4 cubic feet
d) 1 cubic foot

The answer is D. 1 cubic foot.

Step-by-step explanation:

To solve for the volume of a cube, use the formula V= . This is the formula because the volume of a cube formula equals length times width times height. Since the length, width, and height are all the same values, the simplest volume of a cube formula is .

Next, plug in the information from the question into the formula, which will look like V= . Then, solve the equation, and the final answer will be 1 cubic foot.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
