tolong dikerjakan dengan benar dan teliti soalnya soal ph
1. a. V = s x s x s
= 12 x 12 x 12
= 1.728 cm³
b. V = 1/3 x L.alas x t
= 1/3 x 12 x 12 x (20 - 12)
= 1/3 x 12 x 12 x 8
= 384 cm³
c. V = 1.728 + 384
= 2.112 cm³
2. a. V = πr²t
= 22/7 x 7 x 7 x 15
= 2.310 cm³
b. V = 1/3 πr²t
= 1/3 x 22/7 x 7 x 7 x (39 - 15)
= 1/3 x 22/7 x 7 x 7 x 24
= 1.232 cm³
c. V = 2.310 + 1.232
= 3.542 cm²
