Answer:
(a) 240 balls.
(b) 720 balls.
Step-by-step explanation:
We have been given that Piper saw a large box of ping pong balls with 48 balls in each layer.
(a) To find the number of balls in 5 layers, we will multiply 5 by 48 as:
[tex]\text{Number of balls in 5 layers}=5\times 48[/tex]
[tex]\text{Number of balls in 5 layers}=240[/tex]
Therefore, the box with 5 layers will have 240 balls.
(b) To find the number of balls in 15 layers, we will multiply 15 by 48 as:
[tex]\text{Number of balls in 15 layers}=15\times 48[/tex]
[tex]\text{Number of balls in 15 layers}=720[/tex]
Therefore, the box with 15 layers will have 720 balls.
