Calculate volume of concrete in cm3 if water trough hold 485 litres of water.. dimensions L=3m,w68,5 cm,h40cm ,1 litre=1000 cm3 calculate volume ?

First, we need to convert the dimensions of the water trough from meters and centimeters to centimeters:

Length (L) = 3m = 300cm
Width (W) = 68.5cm
Height (H) = 40cm

Next, we calculate the volume of the water trough in cm3:

Volume = Length x Width x Height
Volume = 300cm x 68.5cm x 40cm
Volume = 822000 cm3

Since 1 litre is equal to 1000 cm3, we can calculate the volume of concrete in cm3 that the water trough can hold:

Volume of concrete = 485 litres x 1000 cm3/litre
Volume of concrete = 485000 cm3

Therefore, the water trough can hold 485,000 cm3 of concrete.

1. Convert the dimensions to cm:

- L = 3m = 300 cm
- W = 68.5 cm
- H = 40 cm

2. Calculate the volume of the water trough in cm³:

- Volume = L x W x H
- Volume = 300 cm x 68.5 cm x 40 cm
- Volume = 822,000 cm³

3. Since 1 litre is equal to 1000 cm³, the volume of water in the trough is:

- 485 litres = 485 x 1000 cm³
- Volume of water = 485,000 cm³

4. Therefore, the volume of concrete in the trough is:

- Volume of concrete = Volume of trough - Volume of water
- Volume of concrete = 822,000 cm³ - 485,000 cm³
- Volume of concrete = 337,000 cm³
