Question

jawab dong kakkkkk plissssssaassasssssss​

Answer 1

Jawaban:

1) V = 72

2) V = 68

3) t = 15

4) LA = 36

5) t = 27

Penjelasan dengan langkah-langkah:

1) V= 1/3xLAxT = 1/3x18x12 = 72

2) V= 1/3x34x6 = 68

3) 130 = 1/3x26xt

390= 26xt

t = 15

4) 432 = 1/3xLAx36

432 = LAx12

LA = 36

5) 675 = 1/3x75xt

675=25xt

t=27

Answer 2

1. Diketahui :

• L.alas = 18
• t = 12

Ditanya :

• Volume Limas?

Jawab :

V = ⅓ × L.alas × t

V = ⅓ × 18 × 12

V = 6 × 12

V = 72 (satuan dicantumkan)³

2.

Diketahui :

• L.alas = 34
• t = 6

Ditanya :

• Volume Limas?

Jawab :

V = ⅓ × L.alas × t

V = ⅓ × 34 × 6

V = 34 × 2

V = 68 (satuan dicantumkan)³

3.

Diket :

• V = 130
• L.alas = 26

Ditanya :

• t...?

Jawab :

V = ⅓ × L.alas × t

130 = ⅓ × 26 × t

3(130) = 26t

390 = 26t

390/26 = t

15 = t

4.

Diket :

• V = 432
• t = 36

Ditanya :

• L.alas...?

Jawab :

V = ⅓ × L.alas × t

432 = ⅓ × L.alas × 36

432 = 12L.alas

432/12 = L.alas

36 = L.alas

5.

Diket :

• V = 675
• L.alas = 75

Ditanya :

• t...?

Jawab :

V = ⅓ × L.alas × t

675 = ⅓ × 75 × t

675 = 25t

675/25 = t

27 = t
