Answer:

Step-by-step explanation:

I think your question is missing key information and the one below is similar to yours. Hope it will find you well:

"Alex has a block of wood that is in the shape of a rectangular prism dimensions 70 cm by 50 cm by 30 cm.  He cuts a 10-cm square hole through the center of the prism. What is the volume of the remaining solid?

Here is my answer:

The volume of the rectangular prism: 70∗50∗30=105000 cm^{3}

The volume  in the center (intersection of “square holes”): 10∗10∗10=1000 cm^{3}

=> the volume of the remaining solid = The volume of the rectangular prism - The volume  in the center = 105000 - 1000 = 104000cm^{3}
