------------------------------
Luas tabung
= pi x d x t + pi x r^2
= 22/7 × 14 × 10 + 22/7 x 7 x 7
= 440 + 154
= 594cm^2
343 = s³
s = ∛343
= 7cm
L = s x s
= 7 x 7
= 49 cm²
luas seluruh bidang sisi kubus = 6 x 49
= 294cm²
L permukaan tabung tanpa tutup = pi x r ( r + t )
=22/7 x 7 ( 7 + 10 )
= 22 x 17
= 374cm²
