You need to calculate the volume of a cylinder.
What is the formula for the volume of a cylinder?

igreen · Answer

Formula for Volume of a Cylinder:

$V = \pi r^2 h$

what @iGreen said

mathstudent55 · Answer

The volume of a cylinder is found by multiplying the square of the radius by the height and by pi.

igreen · Answer

Info:

Diameter of 1 Gold Cylinder: 6.19

Radius = Half the Diameter

Half of 6.19 is 3.095.

Height is 6.

$V = \pi r^2 h$

Plug in the values:

$V \approx (3.14)(3.095)^2(6)$

$V \approx (3.14)(9.58)(6)$

$V \approx (30.08)(6)$

$V \approx 180.48$

igreen · Answer

Volume of the Gold cylinders is approximately 180.

Volume of each solid block is 360.

So it will take approximately 2 Gold cylinders to make one solid block.
