--------------------------------------------------------------------

The volume of a cylinder is pi%2Ar%5E2%2Ah .

The volume of a cube with the edge of a centimeters is a%5E3 cm%5E3.

So, a = root%283%2C+3.14%2A5%5E2%2A20%29 = root%283%2C+1570%29 = 11.62 cm.

Hi there,
Volume of a cylinder = Pi x r^2 h
= Pi x 5^2 x 20 = 1570.8 cm^3 (1 decimal place)
Volume of a cube = length x breadth x height
OR x^3 as all sides are the same.
x^3 = 1570.8
x = cube root of 1570.8 = 11.6 cm
So length = breadth = height = 11.6 cm.
11.6 cm ^3 = 1570.8 cm^3
Hope this helps :-)
