Kakak, tolong pls pakai cara ya plss plss

1. p = 4 m = 400 cm

l = 50 cm

t = 2 cm

V = p x l x t

= 400 x 50 x 2

= 40.000 cm³

2. L = K.alas x t

= 4 x 50 x 300

= 60000 cm²

= 6 m²

3. t = V : ( p x l)

= 480 : (20 x 8)

= 480 : 160

= 3 cm

4. pl + pt + lt = L : 2

5×2 + 5xt + 2xt = 202 : 2

10 + 5t + 2t = 101

7t + 10 = 101

7t = 101 – 10

= 91

t = 91/7

= 13 cm

5. L = 6s²

= 6 x 100 x 100

= 60.000 cm²
