2. Tinggi Tabung = Volume ÷ Luas Alas
= 38.936 ÷ 1256
= 31 Cm
3. Selisih Volume Prisma = Volume 2 - ( Selisih ) Volume 1
= 43.200 - 34.560
= 8640 Cm³
Volume 1 = Luas Alas × Tinggi
= ( × A × T ) × Tinggi Prisma
= ( × 48 × 36 ) × 40
= ( 24 × 36 ) × 40
= 864 × 40
= 34.560 Cm³
Volume 2 = Luas Alas × Tinggi
= ( × A × T ) × Tinggi Prisma
= ( × 48 × 36 ) × 50
= ( 24 × 36 ) × 50
= 864 × 50
= 43.200 Cm³
4. Ukuran Persegi = √ Luas Gabungan - Luas Persegi Panjang
= √ 1056 - ( P × L )
= √ 1056 - ( 25 × 32 )
= √ 1056 - 800
= √ 256
= 16 Cm
= 16 Cm × 16 Cm
5. Luas Bangun = Luas I + Luas II
= 270 + 200
= 470 m²
Luas I ( Trapesium ) = × ( Jumlah Sisi Sejajar ) × Tinggi
= × ( 25 + 20 ) × 12
= × 45 × 12
= 45 × 6
= 270 m²
Luas II ( Segitiga ) = × A × T
= × 20 × 20
= × 400
= 200 m²
