Question 766511
<pre>

Volume of the wire = base area * length

Base radius = 0.25/2 = 0.125 cm
Length = 33 m = 3300 cm

volume = {{{pi * (0.125)^2 * 3300}}} = 162}}} (rounding off to nearest whole number)

For the copper block, let the length be x. Then the width = 2x and height = 3x
(since the ratio of the dimensions is 1:2:3)

Volume of the block = x*2x*3x = 6*x^3 = 162

{{{x^3 = 162/6 = 27}}}

x = 3 cm

So the dimensions of the block are 3 cm, 6 cm and 9 cm.

Hope you got it :)
