tolong jawab no 26 dan 27

26.
p = 6 cm
L= 3 cm
T= 4 cm
[tex]luas \: balok \: = 2 \times ((p \times t )+ (p \times l )+( l \times t))[/tex]
maka
[tex] = 2 \times ((6 \times 4) + (6 \times 3) + (3 \times 4)) \\ = 2 \times (24 + 18 + 12) \\ = 2 \times 54 \\ = 108 {cm}^{2} [/tex]
27.
[tex]volume \: tabung = \pi \times t\times {r}^{2} [/tex]
maka:
[tex] = \frac{22}{7} \times 58 \times 21 \times 21 \\ = 22 \times 58 \times 21 \times 3 \\ = 1276 \times 63 \\ = 80388 {cm}^{3} [/tex]

1) 2 (pl + pt + lt)
2 (6.4 +6.3+ 3.4)
2 (24+ 18 + 12)
108

2) phi×r×t
22/7 ×21×21×58
