Nomor 1 p = m/v = 675/250 = 2,7 gr/cm3 = (2,7 / 1000) : (1/1.000.000) = (2,7 × 1.000.000) : (1 × 1000) = 2.700 kg/m3 nomor 2 v kubus = S x S x S = S pangkat 3 = 2 × 2 × 2 = 8 m kubik p = 150/8 = 18,75 kg/m3 nomor 3 m = p x v = 7,9 × 2.000 = 15.800 gr = 15,8 kg nomor 4 m = p x v = 3,0 × 375 = 1125 cm3
p = m/v
= 675/250
= 2,7 gr/cm3
= (2,7 / 1000) : (1/1.000.000)
= (2,7 × 1.000.000) : (1 × 1000)
= 2.700 kg/m3
nomor 2
v kubus = S x S x S = S pangkat 3
= 2 × 2 × 2 = 8 m kubik
p = 150/8
= 18,75 kg/m3
nomor 3
m = p x v
= 7,9 × 2.000
= 15.800 gr = 15,8 kg
nomor 4
m = p x v
= 3,0 × 375
= 1125 cm3
