A rectangular water tank of base 80 cm ✖ 90 cm contains water up to depth of 40 cm. How many litres are there in the tank?
just multiply the dimensions.
1L = 1000 cm^3
A recipe for cookies calls for 7 and one half 7 1/2 cups of flour. If the recipe is for 2 dozen cookies, how much flour is needed for 13 dozen cookies?
To find the volume of the water tank in liters, we need to multiply the area of the base with the height of the water.
1. Convert the dimensions to meters: 80 cm = 0.8 meters and 90 cm = 0.9 meters.
2. Calculate the area of the base: 0.8 meters * 0.9 meters = 0.72 square meters.
3. Convert the height to meters: 40 cm = 0.4 meters.
4. Calculate the volume of the water: 0.72 square meters * 0.4 meters = 0.288 cubic meters.
To convert cubic meters to liters, multiply by 1000 since 1 cubic meter is equal to 1000 liters.
5. Convert the volume from cubic meters to liters: 0.288 cubic meters * 1000 = 288 liters.
Therefore, there are 288 liters of water in the tank.
