Question

A solid cubical block of fine wood costs $256 our at $500 per metre³. Find the volume and the length of each side.

Answer 1

Total Cost = Volume × Rate
$256 = Volume × $500/m^3
Volume = m^3/$500 × $256
Volume = 125/64 m^3

Volume of a cube = (side)^3 = 125/64 m^3
side = [125/64 m^3]^1/3
side = 5/2m
side = 2.5m
