1A.

Luas Alas (A)

= 12 × 3

= 36 Cm²

= 0,0036 m².

P = F/A

P = 30/0,0036

P = 8.333,33 N/m².

1B.

Luas Alas (A)

= 8 × 3

= 24 Cm²

= 0,0024 m².

P = F/A

P = 30/0,0024

P = 12.500 N/m².

1C.

Luas Alas (A)

= 12 × 8

= 96 Cm²

= 0,0096 m².

~Koreksi~

~Opung~

P = F/A

P = 30/0,0096

P = 3.125 N/m².
