if the length of each edge in a cube is increased by the same percent and the result was a cube that had 25% more volume than it originally had, by what percentage were the edges increased
Added by Scott C.
Step 1
If we increase the length of each edge by "y" percent, then the new length of each edge will be (x + (y/100)x) = x(1 + y/100). The new volume of the cube will be (x(1 + y/100))^3 = x^3(1 + y/100)^3. We are given that the new volume is 25% more than the original Show more…
