a) Volume Kolam Renang

VI = P x L x T VIV = Luas alas x tinggi prisma

= ( x 8 x 3) x 20 VV = P x L x T

= 240 m = 240.000 L = 4.480 m = 4.480.000 L

VIII = P x L x T Volume gabungan = VI + VII + VIII + VIV + VV
= 160.000 + 240.000 + 960.000 +
= 20 x 8 x 6

= 960 m = 960.000 L 1.800.000 + 4.480.000
= 7.640.000 L

Jadi, volume kolam renang tersebut adalah 7.640.000 L 50
