Question

tolong bantu jawab ya kakak!!
makasih​

Answer 1

Penjelasan dengan langkah-langkah:

v = p × l × t

v = 30 × 10 × 15

v = 300 × 15

v = 4.500cm³

v = ⅓ × p × l × tp

v = ⅓ × 30 × 10 × ( 40 - 15 )

v = ⅓ × 30 × 10 × 25

v = 10 × 10 × 25

v = 2.500cm³

=======================

volume gabungan

= 4.500 + 2.500

= 7.000cm³

Answer 2

V limas = ⅓ × luas alas × tinggi

V limas = ⅓ × ( 30 cm × 10 cm ) × ( 40 cm - 15 cm )

V limas = ⅓ × 300 cm × 25 cm

V limas = ⅓ × 7.500 cm

V limas = 2.500 cm³

V balok = p × l × t

V balok = 30 cm × 10 cm × 15 cm

V balok = 300 cm × 15 cm

V balok = 4.500 cm³

Maka,

V gabungan = V limas + V balok

V gabungan = 2.500 cm³ + 4.500 cm³

V gabungan = 7.000 cm³
