Heather builds a rectangular prism with 3 layers of unit cubes. each layer of her prism has 10 unit cubes. explain why the volume of heather’s prism is said to be 30 cubic units.

Trapezoid tuvw is shown on the coordinate plane below: trapezoid tuvw on the coordinate plane with ordered pairs at t 4, 6, at u 7, 6, at v 7, 3, at w 2, 3. if trapezoid t'u'v'w' represents trapezoid tuvw reflected over the y-axis, the ordered pair of w' is (note: you must include parentheses, a comma, and a space after the comma when typing the ordered pair.)
