30×20=600см^2

Answer 2

Calculation of the Surface Area of an Aquarium

To calculate the surface area of the lateral sides of an aquarium, we need to find the sum of the areas of all four sides.

Given: - Length of the aquarium = 30 cm - Width of the aquarium = 25 cm - Height of the aquarium = 20 cm

To calculate the surface area, we need to find the area of each side and then sum them up.

Calculation:

1. Area of the side with length 30 cm and height 20 cm: - Area = Length x Height = 30 cm x 20 cm = 600 cm².

2. Area of the side with width 25 cm and height 20 cm: - Area = Width x Height = 25 cm x 20 cm = 500 cm².

3. Since the aquarium has four sides of equal dimensions, we can multiply the area of one side by 4 to get the total surface area of the lateral sides: - Total surface area = 4 x (600 cm² + 500 cm²) = 4 x 1100 cm² = 4400 cm².

Answer:

The surface area of the lateral sides of the aquarium is 4400 cm².
