Question

The volume of a rectangular block of sides 1, 2, 3cm changes when each side is extended by the same length to make a larger block. Taking the extension as x cm
l = 2 + x
b = 1 + x
h = 3 + x

Answer 1

Step-by-step explanation:

To find the width of a rectangle, use the formula: area = length × width. Just plug the area and length of the rectangle into the formula and solve for the width. If you don't have the area, you can use the rectangle's perimeter instead. In that case, you would use the formula: perimeter = 2 × length plus 2 × width.
