Question

A box is to be constructed by cutting oit equal squares from the corners of a 30-cm square piece of card board and turning up the sides.

1.write a function V (x) for the volume of the box.
2.What will be the volume of the box if x=6cm?
3.For what value of x will the volume of the box equal 1568cm³?

Answer 1

Thank you

Answer 2

V(x) = (30-2x)^2 * x
Now you can solve for V(6) and
(30-2x)^2 * x = 1568
