Question

volume bangun di atas adalah​

Answer 1

Jawaban:

A

Penjelasan dengan langkah-langkah:

Volume bangun

= luas permukaan x tinggi

= [(4 cm × 3 cm)/2] x 7 cm

= (12 cm²/2) x 7 cm

= 6 cm² x 7 cm

= 42 cm³

Jawaban: A

Answer 2

Jawaban:

Penyelesaian :

• Tinggi prisma (tp) = 7 cm
• Tinggi segitiga (ts) = 4 cm
• Alas segitiga (as) = 3 cm

Volume prisma segitiga

[tex] \sf Volume = (\frac{1}{2} \times luas \: alas) \times tp[/tex]

[tex] \sf Volume = ( \frac{1}{2} \times as \times ts) \times tp[/tex]

[tex] \sf Volume = ( \frac{1}{2} \times 4 \times 3) \times 7[/tex]

[tex] \sf Volume = ( \frac{1}{2} \times 12) \times 7[/tex]

[tex] \sf Volume = 6 \times 7[/tex]

[tex] \sf Volume = 42 \: {cm}^{3} [/tex]
