Answer:

728 cm²

Step-by-step explanation:

the surface area is the area of the 6 faces.

the opposite rectangular faces are congruent , then

SA = front/ back + sides + top/ bottom

= 2(14 × 14) + 2(6 × 14) + 2(14 × 6)

= 2 × 196 + 2 × 84 + 2 × 84

= 392 + 168 + 168

= 728 cm²

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the given curves about the

ipn [44]

For each $x$ in the interval $0\le x\le2$ , the corresponding shell has radius $x+9$ (horizontal distance from $x$ to the rotation axis) and height $8-x^3$ (vertical distance between $y=8$ and $y=x^3$ ). A shell of radius $r$ and height $h$ has area $2\pi rh$ , so the volume is
