Calculate the volume of a rectangular parallelepiped, the base area and the height of which are 136 cm2, 5cm; 16 cm2, 8cm.

According to the condition of this task, it is required to calculate the volume of a rectangular parallelepiped if its base area and height are known. As you know, the volume of a rectangular parallelepiped is equal to the product of the area of its base by its height. Thus, we can compose expressions and perform calculations of the volumes of the given figures:

136 * 5 = 680 (cm3);

16 * 8 = 128 (cm3);

Answer: The volumes of the given rectangular parallelepipeds are equal: 680 cm3, 128 cm3.
