Question

how do engineers solve the problem of using the smallest possible amount of explosive? problem: engineers want to use the smallest possible amount of explosive. solution:? engineers guess an amount that is exactly what they need. engineers try to keep the cost down for explosives. engineers test an amount of explosive on a column. engineers drill a hole in a column to demolish it.

Explanation:

Engineers need to find the right amount of explosive. Testing an amount on a column helps them determine the smallest - effective quantity. Guessing exactly what is needed is difficult without testing. Keeping cost down is a related but not the direct solution to finding the smallest amount, and drilling a hole to demolish is not related to finding the smallest amount of explosive.

Answer:

Engineers test an amount of explosive on a column.
