I have solved your problem

Step-by-step explanation:

Surface area of cylinder:

The formula is SA= 2πr² + 2πrh

where r is the radius and h is the height

Here, radius would be 30 since balls have diameter 60 and radius is half of that.

height is the diameter of 4 balls line-by line, so height is 60*4 = 240

Now, plugging into the formula, we get:

SA = 2πr²+2πrh

SA = 2π(30)²+ 2π(30)(240)

SA= 50, 868

Surface Area of rectangular prism:

The surface area of rectangular prism is the area of all the rectangular surfaces (6 of them).

Area of top and bottom = (60+60)*(60+60)2 = 120*120 * 2 = 28,800

Area of 2 sides = 2 * (60*120) = 14,400

Area of front and back = 2 * (60*120) = 14,400

Total Surface Area = 28,800 + 14,400 + 14,400 = 57,600

Thus, cylinder has smaller surface area.
