Question

A solid cubical block of fine wood costs Rs. 256 at Rs. 500 per m cube. Find its volume and the length of each side

Answer 1

According to question,
Cost of one m³ of cloth = Rs 500
Cost of the cube =256 RS

Therefore, volume of the cube = cost of the cube/ cost of 1m³ of cloth
= 256/500m³
= 0.512m³

Now to convert it into cm³ we multiply 1000000 to it.
Thus, 0.512m³ = 0.512 x 1000000 = 512000cm³
So we have the volume as 512000cm³. Thus the length of the side of the cube = ∛512000
= 80cm

Hope that helps !!
