The height of the prism is 2.25 \ in

Explanation:

It is given that the area of the cross section of the rectangular prism is 45 square inches.

Length of the rectangular prism is 5 \ in

Width of the rectangular prism is 5 \ in

To determine the height of the prism, let us substitute these values in the formula SA=(2l+2w)h , we get,

45=(2(5)+2(5))h

Multiplying the terms within the bracket, we get,

45=(10+10)h

Adding the terms within the bracket, we have,

45=20h

Dividing both sides by 20, we get,

2.25=h

Thus, the height of the rectangular prism is 2.25 \ in
