Options

What kind of metal are the coins made of?

Bronze (8700 kg per cubic meter)

Silver (10500 kg per cubic meter)

Lead (11300 kg per cubic meter)

Gold (19300 kg per cubic meter)

Answer:

Gold

Step-by-step explanation:

Density is mass per unit volume of an object hence calculated as

d=m/v

Where m is the mass of an object, v is the volume and d is rhe density.

Substituting 4825 Kg for m and 0.25 m3 for v then

D=4825/0.25=19300 kg/m3

From the options given, this density is equivalent to that of gold.
