A right prism is shown. The volume of the right prism in cubic centimeters is _____.

Isabelle is designing two cereal boxes that will have the same volume. Box A will be a right rectangular prism with length 10 cm, width 8 cm, and height 20 cm. Box B will be a right triangular prism as shown. Isabelle wants to determine the height that will make the volume of Box B the same as the volume of Box A. Determine whether the step below in Isabelle's solution is correct:

Step 1: The volume of Box A is 10 x 8 x 20 = 1,600 cm³

• True
• False

• True
• False
