Question

 Помогите решить.Аквариум имеет форму прямоугольного параллелепипеда. Его боковые стенки стеклянные. Определи объем аквариума и площадь поверхности стекла если длина аквариума 50 см ширина 30 см а высота 40см. 

Answer 1

Calculation of the Volume of the Aquarium

To determine the volume of the aquarium, we can use the formula for the volume of a rectangular prism, which is given by:

Volume = Length x Width x Height

Given that the length of the aquarium is 50 cm, the width is 30 cm, and the height is 40 cm, we can substitute these values into the formula:

Volume = 50 cm x 30 cm x 40 cm

Calculating this expression, we find:

Volume = 60,000 cm³

Therefore, the volume of the aquarium is 60,000 cubic centimeters.

Calculation of the Surface Area of the Glass

To determine the surface area of the glass, we need to calculate the area of each of the six faces of the rectangular prism and then sum them up.

The formula for the surface area of a rectangular prism is given by:

Surface Area = 2lw + 2lh + 2wh

where l is the length, w is the width, and h is the height.

Given that the length of the aquarium is 50 cm, the width is 30 cm, and the height is 40 cm, we can substitute these values into the formula:

Surface Area = 2(50 cm x 30 cm) + 2(50 cm x 40 cm) + 2(30 cm x 40 cm)

Calculating this expression, we find:

Surface Area = 3,800 cm²

Therefore, the surface area of the glass in the aquarium is 3,800 square centimeters.
