Problem Statement:
Write appropriate measurements in the blank spaces:

Solution Method:
- Formula for calculating the area of a rectangular prism base: S = a x b
=> In words: The area of the rectangular prism base is the product of its length and width.
- Formula for calculating the lateral surface area of a rectangular prism: S_xq = 2h. (a + b)
=> In words: The lateral surface area of the rectangular prism is the product of its height and the perimeter of its base.
- Formula for calculating the volume of a rectangular prism: V = a x b x h
=> In words: The volume of the rectangular prism is obtained by multiplying its length by its width, then multiplying by its height.

Answer:
- Rectangular prism (1):
Base area: 11 x 10 = 110 cm²
Lateral surface area: (11 + 10) x 2 x 6 = 252 cm²
Volume: 11 x 10 x 6 = 660cm³
- Rectangular prism (2):
Base area: 0.4 x 0.25 = 0.1 m²
Lateral surface area: (0.4 + 0.25 ) x 2 x 0.9 = 1.17 m²
Volume: 0.4 x 0.25 x 0.9 = 0.09 m³
- Rectangular prism (3):

We obtain the following table as a result:
