Question

The rectangular prism is to be sliced perpendicular to the shaded face and is to pass through point B, parallel to the front face. What will the dimensions of the rectangular cross section be?

Answer 1

The dimensions of the rectangular cross section will be 10 centimeters by 18 centimeters

Explanation:

As ,we know

The rectangular cross section is parallel to the front face

Which clearly states that

The dimensions of the rectangular cross section is congruent with the dimensions of the front face

Lets assume that dimensions of the front face are 10 centimeters by 18 centimeters

Then ,The dimensions of the cross section will also be 10 centimeters by 18 centimeters

Hence we can say that the dimensions of the rectangular cross section will be 10 centimeters by 18 centimeters
