Aslice is made perpendicular to the base of a right rectangular prism as shown.

what is the area of the resulting two-dimensional cross section?

drag and drop the answer into the box.

You would forget the height (7 mm). The reason for this is because it is now a rectangle and not a rectangular prism. To find the area of a rectangle, you multiply length by width. In this case, 4 mm times 12 mm. The answer would result in 48mm squared.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
