Answer:
The toy chest hold 90 building blocks.
Step-by-step explanation:
A student made a toy chest for his baby sister's square building blocks.
In the box only six layers of blocks can fit and each layer has 15 blocks.
If a box can hold only 6 layers and in each layer there is 15 blocks
To calculate the total number of building blocks we have to multiply 15 blocks to 6 layer.
so total blocks = 15 × 6 = 90 building blocks.
Or you can add 15 by 6 times. ( 15 + 15 + 15 + 15 + 15 + 15 = 90 )
The toy chest hold 90 building blocks.
