Naomi made a triangular pyramid from cardboard. the triangular base has a height of 4 inches and a base length of 15 inches. the height of the pyramid is 6 inches. if naomi wants to double the volume of the pyramid, which method can she use? she can double the base length of the base so that the new volume is 120 cubic inches. she can double the base length of the base so that the new volume is 360 cubic inches. she can double both the base length and height of the base so that the new volume is 240 cubic inches. she can double both the base length and height of the base so that the new volume is 720 cubic inches.

Consider the following geometry problems in 3-space enter t or f depending on whether the statement is true or false. (you must enter t or f -- true and false will not work.) f equation editorequation editor 1. a plane and a line either intersect or are parallel t equation editorequation editor 2. two planes parallel to a third plane are parallel f equation editorequation editor 3. two lines either intersect or are parallel f equation editorequation editor 4. two planes orthogonal to a third plane are parallel f equation editorequation editor 5. two planes orthogonal to a line are parallel f equation editorequation editor 6. two planes either intersect or are parallel f equation editorequation editor 7. two lines orthogonal to a third line are parallel t equation editorequation editor 8. two lines parallel to a third line are parallel t equation editorequation editor 9. two planes parallel to a line are parallel f equation editorequation editor 10. two lines parallel to a plane are parallel f equation editorequation editor 11. two lines orthogonal to a plane are parallel
