Question

Tolong dijawab ya yg no 4
Makasih kakak kakakkk:)​

Answer 1

a. panjang kawat 1,8m = 180 cm

panjang rusuk = 180 cm : 12 = 15 cm

b. Lp Kubus= 6 x s²= 6 x 15²= 6 x 225= 1.350 cm²

c.V kubus = S³ = 15³= 3.375 cm3

Answer 2

Diketahui : Panjang kawat = 1,8 m = 180 cm

A. jumlah rusuk kubus = 12

Maka panjang rusuk = 180/12 = 15 cm

B. Luas kubus = 6 x S x S

= 6 x 15 x 15

= 1.350 cm^2

C.Volume kubus = S x S x S

= 15 x 15 x 15

= 3.375 cm^3
