Luas permukaan balok

lp = 2 × (pl + pt + lt )

lp = 2 × ((25×14) + (25×12) + (14×12))

lp = 2 × ( 350 + 300 + 168 )

lp = 2 × ( 650 + 168 )

lp = 2 × 818

lp = 1.636 cm3

Volume tabung

[tex]v = \pi \times r \times r \times t[/tex]

[tex]v = \frac{22}{7} \times 56 \times 56 \times 48[/tex]

[tex]v = \frac{22 \times 56 \times 56 \times 48}{7} [/tex]

[tex]v = \frac{1.232 \times 56 \times 48}{7} [/tex]

[tex]v = \frac{68.992 \times 48}{7} [/tex]

[tex]v = \frac{3.311.616}{7} [/tex]
