Ametronome is a device that ticks at adjustable intervals to keep time when playing music. the metronome on ryan’s piano has the basic shape below.

if the metronome was created out of a piece of solid wood, what is the minimum amount of solid wood that was used? fyi, the number that is hard to see is 20.5

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the answer i believe is 27 units.
