Cannonballs are stacked In a pyramid shape with a base of 5 cannonballs on a side. How many cannonballs in all are in the stack
Vadim26 [7]

Answer:

The total number of balls in the pyramid will be 55.

Step-by-step explanation:

Cannonballs are stacked In a pyramid shape with a base of 5 cannonballs on a side.

Therefore, at the base, the number of balls is 5².

In the layer above the base layer, there are 4 balls on each side.

So, in the layer above the base layer, the number of balls is 4².

Similarly, in the next levels, the number of balls will be 3², 2² and 1.

Therefore, the total number of balls in the pyramid will be (5² + 4² + 3² + 2² + 1) = 55. (Answer)
