An image of a rectangular prism is shown below:

A right rectangular prism is shown.

Part A: A cross section of the prism is cut with a plane parallel to the base. What is the name of the shape created by the cross section? Explain your answer.

The shape created by the cross section would be a rectangle. This is because the cross section is parallel to the base of the prism, so the shape created will have the same dimensions as the base of the prism, which is a rectangle.

Since the cross section maintains the same shape as the base, it will also have two pairs of parallel sides and four right angles, making it a rectangle.

say that again but in 7 grade words

The shape created by the cross section is a rectangle because the cut is parallel to the base of the prism, so it has the same shape and features as the base.

A right rectangular prism is shown.
Part B: If a cross section of the prism is cut diagonal to the base, what would be the shape of the resulting cross section? Explain your answer

The shape of the resulting cross section would be a parallelogram. This is because cutting the prism diagonally to the base would create a shape with two pairs of opposite sides that are parallel, but the angles may not necessarily be right angles. This type of shape is called a parallelogram.
