*Nmr 1*
Vol kubus + vol balok
= (20^3 + 50×20×20)mm^3
= (8000 + 20000)mm^3
= 28000 mm^3
= 28 cm^3

*Nmr 2*
Vol prisma + vol kubus
= [(8×17 / 2)×17 + 17^3] cm^3
= (1156 + 4913) cm^3
= 6069 cm^3

*Nmr 3*
Vol prisma + vol tabung
= [(5×5)/2 × 12 + 22/7×(7/2)^2×20] dm^3
= (150 + 770) dm^3
= 920 dm^3
= 920 liter

*Nmr 4*
Vol prisma + vol balok
= [(15×15)/2 × 50 + 15×20×70] cm^3
= (5625 + 21000) cm^3
= 26625 cm^3

*Nmr 5*
Vol kubus + vol tabung
= [25^3 + 22/7×(14/2)^2×15] cm^3
= (15625 + 2310) cm^3
= 17935 cm^3
