90 points! part 1: (the volume of the two pyramids that i solved are both 160cm) write in symbols how the volume of one of the three right pyramids relates to the volume of the entire prism. use y for the volume of the pyramid and r for the volume of the prism. explain what the symbols mean in words. how does this relate to the volume formulas for prisms and pyramids? part 2: (the volume of the triangular pyramid is 7.7, the prism is 22.86) write in symbols how the volume of the triangular pyramid relates to the volume of the triangular prism. use y for the volume of the pyramid and r for the volume of the prism. explain what the symbols mean in words. you!

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
