A solid cubical block of fine wood costs 256 at 500 per m3. Find its volume and the length of each side.

It is given that,

Cost of wood = Rs. 500/m3


Also,


Cost of the given block = Rs 256


We know that,


Volume of cube = a3


Therefore,


Volume of the given block = a3 =


= 0.512 m3


= 512000 cm3


Also,


Length of its edge = a =


= 0.8 m


= 80 cm
