A rectangular prism measures LaTeX: 7\frac{1}{2}7 1 2cm by 12 cm by LaTeX: 15\frac{1}{2}15 1 2 cm. Calculate the number of cubes with edge length LaTeX: \frac{1}{2}1 2 cm that fit in this prism.
What is the volume of the prism in LaTeX: cm^3c m 3? Show your reasoning. If you are stuck, think about how many cubes with LaTeX: \frac{1}{2}1 2-cm edge lengths fit into LaTeX: 1\:cm^31 c m 3.
thank you in advance for your help

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after  2  hours of driving after her coffee break, her distance from her house was  210  miles. her average speed during the whole trip was  60  miles per hour.valerie created the equation  y−210=60(x−2)  to represent this situation, where  xx  represents the time in hours from her coffee break and  yy  represents the distance in miles from her house.which graph correctly represents valerie's distance from her house after her coffee break?
