A solid cubical block of fine wood costs Rs 256 at Rs 500 per metercube find its volume and the length of each side?

To find the volume of the solid cubical block, we divide the cost by the price per cubic meter: ( \text{Volume} = \frac{256}{500} = 0.512 , \text{m}^3 ). Since the block is a cube, the volume ( V ) is given by ( V = a^3 ), where ( a ) is the length of each side. Thus, ( a = \sqrt[3]{0.512} \approx 0.8 , \text{m} ). Therefore, the volume is 0.512 m³ and the length of each side is approximately 0.8 m.
