The volume of prism is 308 cm3 and height is 11 cm. The base area of the prism is:

21 cm2 14 cm2 28 cm2 22 cm2

28 cm2

We know that, The volume of the prism = area of its base × height The volume of a prism = 308 cm3  Height = 11 cm. According to the question, 308 = area of its base × 11 Area of its base = 28cm2
