Question 1163392: Build a sugar cube pyramid as follows: First make a 5 x 5 x 1 bottom layer. Then center a 4 x 4 x 1 layer on the first layer, a 3 x 3 x 1 layer on the second layer, and center a 2 x 2 x 1 layer on the third layer. The fifth layer is a single 1 x 1 x 1 cube. Express the volume of this pyramid as a percentage of the volume of a 5 x 5 x 5 cube.

.

Calculate the number of sugar bricks in each layer.


Then add these numbers.


Then compare the sum "n" with  N = 5*5*5, which is the number of the sugar bricks in the cube.


    P =   will be your percentage and your answer.
