Jawaban:
1.) 990 cm³
2.) 1232 cm³
3.) 22 cm
Penjelasan dengan langkah-langkah:
Rumus utk nomor 1 & 2 :
Volume = (Alas x Tinggi ÷ 2) x Tinggi Prisma
Rumus utk nomor 3 :
Tinggi Prisma = Volume ÷ Luas Alas
Luas Alas (Segitiga) = 1/2 x alas x tinggi
1.) Volume
= (9 x 11 ÷ 2) x 20
= 99/2 x 20
= 990 cm³
2.) Volume
= (16 x 7 ÷ 2) x 22
= 56 x 22
= 1232 cm³
3.) Luas Alas Segitiga
= 1/2 x 12 x 10
= 120 cm²
Tinggi Prisma
= 2640 ÷ 120
= 22 cm
Semoga membantu
Volume Prisma
V = Luas alas x tinggi prisma
Luas Segitiga
L = 1/2 x alas x tinggi
Penyelesaian:
1.) a = 9 cm, t = 11 cm, t prisma = 20 cm
V = Luas segitiga x tinggi prisma
V = 1/2 x a x t x t prisma
V = 1/2 x 9 x 11 x 20
V = 990 cm³
2.) a = 16 cm, t = 7 cm, t prisma = 22 cm
V = 1/2 x 16 x 7 x 22
V = 1232 cm³
3.) a = 24 cm, t = 10 cm, V = 2640 cm³
2640 = 1/2 x 24 x 10 x t prisma
2640 = 120 x t prisma
t prisma = 2640/120
t prisma = 22 cm
