Explanation

This is an inverse proportion problem. M1 * D1 = M2 * D2. 10 * 8 = M2 * 0.5. 80 = 0.5 * M2. M2 = 160.

AI explanation

By applying the formula M1D1 = M2D2 for constant work, we have M1 = 10 men, D1 = 8 days, and D2 = 0.5 days. Substituting these values gives 10 * 8 = M2 * 0.5, which simplifies to 80 = 0.5M2. Solving for M2 yields 160, meaning 160 men are needed to complete the construction work in half a day. The result is 160.
