Question

Find the mass of a wooden block if its volume is 70 cubic cm and the density of wood is 8 kg/m^3
56 g
56 kg
0.56 g
56 mg​

Answer 1

Explanation:

1 cubic metre is equal to 10 power minus 6 metrecube

Answer 2

Explanation:

given,

m = ?

V = 70 cm³ = 7 * (10^(-5)) m³

d = 8 kg/m³

formulas

d = m/V _ _ _(1)

putting the value in eq (1)

d = m/V

→ m = dV

→ m = 8 * (7 * (10^(-5))) kg

→ m = 56 * (10^(-5)) * 10³g [1 kg = 10³g]

→ m = 0.56 g

hence m = 0.56 g
