Question

A solid metal cylinder has diameter 60cm and height 28cm.It is melted and recast to 50 equal cubes.Find the edge of each cube to 3 significant figures

Answer 1

V = πr^2h

Once you find the volume of the cylinder, divide by 50 to get the volume of each cube. The edge of each cube will be the square root of the cube volume.

I'll let you do the calculations.

Answer 2

actually, each edge will be the cube root of the volume.

Answer 3

I stand corrected. Thanks.
