Answer:
option D is correct
Explanation:
1) for a cylinder with radius is[tex]\frac{80}{\pi}[/tex]
lateral surface area of cylinder is [tex]2\pi rh[/tex]
[tex]= 2\pi \frac{80}{\pi}*120[/tex]
= 160* 120
2) fro square prism with side 40 mm
lateral surface area = 4ah
= 4*40 * 120
= 160*120
3)for hexagonal with side 20 mm
lateral surface area = 6ah
= 6*20*160
=120* 160
therefore option D is correcrt
