tolong dijawab dong matematika

Rumus luas permukaan persegi = 6 × s×s = 6 x s²
Rumus luas permukaan persegi panjang = 2 x ([pxl] + [pxt] + [l+t])
V persegi = s³
v balok = p x l x t


3) Lp = 6 x 10² = 600
V = 10³ = 1000

4)Lp = 2(15x10) + (15x13) + (10x13)
= 2 x 475 = 950
V= 15 x 10 x 13 = 1950

5)Lp = 2(17x7) + (17x13) + (7x13)
= 2 x 431 = 862
V = 17 x 7 x 13 = 1547

6)Lp = 6 x 12² = 864
V = 12³ = 1728

7)Lp = 2(13x4) + (13x8) + (4x8)
= 2 x 192 = 384
V = 13 x 4 x 8 = 416

8)Lp = 2(19x12) + (19x15) + (12x15)
= 2 x 693 = 1386
V = 19 x 12 x 15 = 3420
