If a metallic cuboid weighs , how much would a miniature cuboid of metal weigh,
If a metallic cuboid weighs \( 16 \mathrm{kg} \), how much would a miniature cuboid of metal weigh, if all dimensions are reduced to one-fourth of the original?
- A. \( 0.25 k g \)
- B. \( 0.50 k g \)
- C. \( 0.75 k g \)
- D. \( 1 k g \)
Step-by-step solution
Weight is proportional to volume. If all dimensions are reduced to one-fourth, new volume = (1/4)^3 = 1/64 of original. New weight = 16 kg × 1/64 = 0.25 kg.
