Answer:
10 square inches
Explanation:
Rectangular prism volume = area of the base * height
Cylinder volume = area of the base * height
Given that the volumes are equal, then the areas are equal.
Area of the base of the rectangular prism = length * width = 5*2 = 10 square inches = Area of the base of the cylinder
Their cross sectional area parallel to the bases are congruent to the bases.
