Tolong bantu jawab ya kak
Penjelasan dengan langkah-langkah:
1)
a. Volume = 20 x 15 x 18/3
= 300 x 6
= 1.800 cm³
b. Volume = 32 x 18 x 18/3
= 576 x 6
= 3.456 cm³
c. Volume = 35 x 24 x 15/3
= 840 x 5
= 4.200 cm³
2)
Volume = 15 x 10 x 15/3
= 150 x 5
= 750 cm³
3)
Luas alas = 12 x 16/2 = 96 cm²
tinggi = 3 x 640/96
= 3 x 5
= 15 cm
4)
Luas alas = 3x100/12
= 300/12
= 25 cm²
panjang sisi alas = √25
= 5 cm
5)
Luas alas = (8+5)x6/2
= 13 x 3
= 39 cm²
Volume = 10 x 39/3
= 10 x 13
= 130 cm³
