Question

Gold in the form of solid cylinders will be molded into solid blocks. Each cylinder has a diameter of 6.18 cm and a height of 6 cm. Each solid block will have a volume of 360 cm3. How many cylinders of gold will it take to mold one block of gold? 1 2 3 4 5

Answer 1

The correct answer for the problem is 2 cylinders. Taking the volume of each cylinder gives a value of around 180 cm^3. Since the volume of one solid block is 360 cm^3, the value should be divided by the volume of the gold cylinder to know how many cylinders are needed. Dividing 360 by 180 gives 2.
