Square Roots and Cube Roots – Side of a Square and a Cube

MathematicsNumbers & ArithmeticAges 14–15

A square with area S has side √S; a cube with volume V has side ∛V. Drag the square's corner or the cube's vertex to change S and V and watch the side update; the bounding panel estimates each root by squeezing it between two integers and then refining one decimal digit at a time, the same method used in the textbook.
