Therefore, ‘a is smaller’. can anyone tell me what i’m doing wrong. i got 2/5 from this question.

A is smaller.

Step-by-step explanation:

SAc of cylindrical container:

Diameter of base: 60 mm

Radius of base: 30 mm

Height of cylinder: 240 mm

SAc = lateral area + area of two bases

SAc = (pi)dh + 2(pi)r^2

SAc = (pi)(60 mm)(240 mm) + 2(pi)(30 mm)^2

SAc = 14,400(pi) mm^2 + 1,800(pi) mm^2

SAc = 16,200(pi) mm^2 which approximately equal to 50,868 mm^2

SAp of prism:

Rectangular prism with L = 120 mm, W = 120 mm, H = 0 mm

SAp = 2(LW + LH + WH)

SAp = 2(120 mm * 120 mm + 120 mm * 60 mm + 120 mm * 60 mm)

SAp = 2(14,400 mm^2 + 7,200 mm^2 + 7200 mm^2)

SAp = 2(28,800 mm^2)

SAp = 57,600 mm^2

The total surface are of the prism is greater than the total surface area of the cylinder.

good luck!
