Arectangular 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.

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
