Question

Сколько ведер N воды емкостью V0=8,0 л. понадобится, чтобы наполнить прямоугольный бак. Длина бака a=1,5м, ширина b=8, дм, высота c=40см.

Answer 1

V= abc = 1,5*0,8*0,4=0,48 м^3
V0= 8 л= 0,008 м^3
N= V/ V0= 0,48/ 0,008=480/8= 60

Answer 2

Calculating the Volume of Water Needed to Fill the Rectangular Tank

To calculate the volume of water needed to fill the rectangular tank, we can use the formula:

Volume = Length × Width × Height

Given: - Length (a) = 1.5 m - Width (b) = 8 dm - Height (c) = 40 cm

First, we need to ensure that all measurements are in the same unit. Let's convert the width and height to meters for consistency.

1 decimeter (dm) = 0.1 meters 1 centimeter (cm) = 0.01 meters

So, the width (b) in meters = 8 dm × 0.1 = 0.8 m And the height (c) in meters = 40 cm × 0.01 = 0.4 m

Now, we can calculate the volume of the rectangular tank using the given dimensions.

Volume = 1.5 m × 0.8 m × 0.4 m

Calculation

Volume = 1.5 m × 0.8 m × 0.4 m = 0.48 cubic meters

Converting Volume to Liters

To convert the volume from cubic meters to liters, we can use the conversion factor: 1 cubic meter = 1000 liters

So, the volume in liters = 0.48 cubic meters × 1000 = 480 liters

Therefore, to fill the rectangular tank with a volume of 0.48 cubic meters, 480 liters of water will be needed.
