$underline{ boxed{ bold{ diketahui}}}$

panjang = 8 dm = 8 × 10 = 80 cm
lebar = 9 dm = 9 × 10 = 90 cm
tinggi = 7 dm = 7 × 10 = 70 cm
sisi = 78 cm
jari – jari = 14 cm

$\ underline{ boxed{ bold{ ditanya}}}$

volume gabungan balok, tabung, dan kubus ?

$\ underline{ boxed{ bold{ jawab}}}$

=> volume balok :

$sf V = p times l times t$

$sf V = 80 times 90 times 70$

$sf V = bold{504.000 : {cm}^{3}} \$

=> volume tabung :

$sf V = pi times {r}^{2} times t$

$sf V = frac{22}{ cancel7} times {14}^{2} times cancel{70} : {}^{10}$

$sf V = 22 times (14 times 14) times 10$

$sf V = 22 times 196 times 10$

$sf V = bold{ 43.120 : {cm}^{3}} \$

=> volume kubus :

$sf V = {s}^{3}$

$sf V = {78}^{3}$

$sf V = 78 times 78 times 78$

$sf V = bold{474.552 : {cm}^{3}} \$

=> volume gabungan :

$sf V_{_{gabungan}} = V_{_{balok}} + V_{_{tabung}} + V_{_{kubus}}$

$sf V_{_{gabungan}} = 504.000 : {cm}^{3} + 43.120 : {cm}^{3} + 474.552 : {cm}^{3}$

$sf V_{_{gabungan}} = bold{1.021.672 : {cm}^{3} }$
