Question

Периметр пола спортивного зала 80 см Найдите объем зала если его длина в три раза больше ширины а высота равна 4 метра 5 см

Answer 1

80:2=40 м длина + ширина
40:4=10 м ширина
10*3=30 м длина
4м5см=4,05м высота
10*30*4,05=1215 м3 объем

Answer 2

Calculating the Volume of the Sports Hall

To find the volume of the sports hall, we can use the given information about its dimensions. The perimeter of the sports hall is 80 meters, the length is three times the width, and the height is 4 meters and 5 centimeters.

Calculating the Width

First, let's calculate the width of the sports hall using the given perimeter.

The formula for the perimeter of a rectangle is: Perimeter = 2 * (length + width)

Given that the perimeter is 80 meters, we can use this formula to find the width.

Using the formula: 80 = 2 * (3w + w) 80 = 2 * 4w 40 = 4w w = 10 meters

Calculating the Length

Since the length is three times the width, we can calculate the length as: Length = 3 * Width Length = 3 * 10 Length = 30 meters

Calculating the Volume

Now that we have the width, length, and height, we can calculate the volume of the sports hall using the formula: Volume = Length * Width * Height

Substituting the values: Volume = 30 * 10 * 4.05 Volume = 1215 cubic meters

So, the volume of the sports hall is 1215 cubic meters.
