Answer:
108
Step-by-step explanation:
The cubes has a volume 1/27 because 1/3 *1/3 *1/3 =1/27. Now we just take 4 and divide by 1/27. Which equals 108 cubes.

Solve for v(t)=0 over the interval [0,2]
<span>sin(pi)<0, try t=pi/2, </span>
<span>3e^(-pi/4)sin(pi)= 0, so the interval 0 to pi/2 the particle travels forward [0,pi/2), then it goes negative for the rest of the interval (pi/2,2) and travels backward. </span>
<span>total distance = |integral 0 to pi/2 v(t) dt| + |integral pi/2 to 2 v(t) dt|
</span>∫[0 to π/2] v(t) dt = ∫[0 to π/2] (3 e^(−t/2) sin(2t)) dt
<span>. . . . . . . . . . . . . = ∫[0 to π/2] (3 e^(−t/2) sin(2t)) dt </span>
<span>. . . . . . . . . . . . . = −6/17 e^(−t/2) (sin(2t) + 4cos(2t)) |[0 to π/2] </span>
<span>. . . . . . . . . . . . . = −6/17 (e^(−π/4) (sin(π) + 4cos(π)) − e^(0) (sin(0) + 4cos(0))) </span>

<span>. . . . . . . . . . . . . = −6/17 (−4e^(−π/4) − 4) </span>
<span>. . . . . . . . . . . . . = 24/17 (e^(−π/4) + 1) </span>

∫[π/2 to 2] v(t) dt = ∫[π/2 to 2] (3 e^(−t/2) sin(2t)) dt
<span>. . . . . . . . . . . . . = ∫[π/2 to 2] (3 e^(−t/2) sin(2t)) dt </span>

<span>when you add absolute values of area you get actual distance traveled: </span>
<span>∫[0 to π/2] v(t) dt − ∫[π/2 to 2] v(t) dt </span>
<span>= 2.05544 − (−0.205938) </span>
<span>= 2.05544 + 0.205938 </span>
<span>= 2.261378 </span>
