Answer:
A is smaller
Step-by-step explanation:
Container A
A = 2π·r·h + 2π·r²
= 2π·r(h + r)
r = d/2 = 54mm/2 = 27 mm
h = 4d = 4·54mm = 216 mm
= 2·3.14·27(216 + 27)
= 169.56×243
= 41203.08 mm²
Container B
A = 4·l·h + 2·l²
l = 2d = 2·54mm = 108 mm
h = d = 54 mm
= 4·108·54 + 2·11664
= 23328 + 23328
= 46656 mm²
Radius = 54/2 = 27
Cylinder:
SA = 2×3.15×27² + 2(3.14×27×(4×54))
Cuboid:
SA = 2[(2×54)²] + 4[54×(2×54)]
