Question

Yg bisa tolong pake cara, bsk dikumpulkan

Answer 1

Saya kerjakan 1-5 ya, no 6-10 dibuat sendiri.. Caranya sama :)

PERHATIKAN bahwa di sini, saya mengasumsikan alas prisma berbentuk persegi panjang. Kalau alasnya berbentuk segitiga, luas alas harus dikali 1/2.

Luas = alas x tinggi alas
Volume = alas x tinggi alas x tinggi prisma

1. a = 50 cm
L = 875 cm²
T = 40 cm
t = L/a = 875/50 = 17,5 cm
V = L x T = 875 x 40 = 35.000 cm³

2. t = 35 cm
T = 9 cm
V = 270 cm³
L = V/T = 270/9 = 30 cm²
a = L/t = 30/35 = 0,85 cm

3. t = 15 cm
L = 105 cm²
T = 5 cm
a = L/t = 105/15 = 7 cm
V = L x T = 105 x 5 = 525 cm³

4. a = 9 cm
t = 6 cm
V = 405 m³
L = at = 9 x 6 = 54
T = V/L = 405/54 = 7,5 cm

5. a = 15 cm
T = 3 cm
V = 135 cm³
L = V/T = 135/3 = 45 cm²
t = L/a = 45/15 = 3 cm
