Penjelasan dengan langkah-langkah:

[tex]\boxed {\sf NOMOR \ 5}[/tex]

Tinggi (t) = 10 cm

Sisi alas (s) = 3 cm

[tex]\sf V = luas \ alas \times t = s \times s \times t\\\sf V = 3 \times 3 \times 10\\\underline {\boxed {\blue {\sf \bf V = 90 \ cm ^3 \ (D)}}}[/tex]

[tex]\boxed {\sf NOMOR \ 6 }[/tex]

Tinggi prisma (t) = 27 cm

Karena alas berbentuk segitiga siku-siku maka berlaku c = sisi terpanjang, a dan b = sisi lainnya. Di sini sisi miring atau c = 17 cm (panjang terbesar) tidak diperlukan.

Tinggi alas segitiga (tΔ) = 15 cm

Panjang alas segitiga (a) = 8 cm

[tex]\sf V = luas \ alas \times t = \frac{a \times tΔ}{2} \times t\\\sf V = \frac{8 \times 15}{2} \times 27\\\sf V = \frac{120}{2} \times 27\\\sf V = 60 \times 27\\\underline {\boxed {\blue {\sf \bf V = 1.620 \ cm^3 \ (C)}}}[/tex]

[tex]\boxed {\sf NOMOR \ 3 }[/tex]

Diameter (d) = 28 cm

Jari - jari (r) = [tex]\sf \frac{1}{2} d = \frac{1}{2} (28) = 14 \ cm[/tex]

Tinggi (t) = 42 cm

[tex]\sf \pi = \frac{22}{7}[/tex]

[tex]\sf V = luas \ alas \times t = \pi \times r^2 \times t\\\sf V = \pi \times r^2 \times t\\\sf V = \frac{22}{7} \times 14^2 \times 42\\\sf V = \frac{22 \times 14 \times 14 \times 42}{7} \\\sf V = \frac{181.104}{7} \\\underline {\boxed {\blue {\sf \bf V = 25.872 \ cm^3 \ (B)}}}[/tex]
