a rectangular cake has a length of 15 inches and a width of 10 inches how many whole square pieceslenghts of 2 1/2 inches can be cut from the cake

24

Step-by-step explanation:

The cake measures 10 inches by 15 inches. If pieces are 2.5 inches long and wide (they are square and equal) then 6 pieces will be cut along the length.

15 / 2.5 = 6

And 4 pieces will be cut along the width.

10 / 2.5 = 4

All together when the entire cake is cut, there will be 4*6 = 24 squares 2.5 inch long pieces.
