Question

The density of lead is 11500kg/m^2 .The dimensions of the lead block is 5cm ×10cm ×20cm. The mass of the block is. a. 10kg.
b. 10.5kg.
c. 11kg.
d. 11.5kg​

Answer 1

Answer:

d. 11.5kg

Explanation:

Density = mass / volume

volume of lead block = 0.05*0.1*0.2

                                   = 0.001m³

density     =m/v

11500        =m/0.001

m              = 11.5kg

Answer 2

Answer:

Density of lead is 11500kg/m^2

dimensions of the lead block is 5cm × 10cm ×20cm

= 0.05 × 0.1 × 0.2

= 0.001 m^2

rho = m/v

11500 = m/0.001

11500 × 0.001

11.5 kg
