Bricks have a mass of 1.75kg each. How many bricks are there in 21/4tonnes
We know that 1 tonne is equal to 1000 kg. Therefore, 21/4 tonnes is equal to:
(21/4) x 1000 = 5250 kg
To find out how many bricks there are in this weight, we need to divide the total weight by the weight of each brick:
5250 kg ÷ 1.75 kg/brick = 3000 bricks
Therefore, there are 3000 bricks in 21/4 tonnes of bricks.
To find out how many bricks are there in 21/4 tonnes, we need to convert tonnes to kilograms and then divide the total mass by the mass of each brick.
First, let's convert tonnes to kilograms. 1 tonne is equal to 1000 kilograms. So, 21/4 tonnes can be converted to kilograms by multiplying it by 1000:
21/4 tonnes * 1000 kg/tonne = (21/4) * 1000 kg = 21 * 250 kg = 5250 kg
Now that we have the mass in kilograms, we can divide it by the mass of each brick (1.75 kg) to find out the number of bricks:
5250 kg / 1.75 kg/brick = 3000 bricks
So, there are 3000 bricks in 21/4 tonnes.
To find the number of bricks in 21/4 tonnes (or 2100 kg), we need to divide the total mass by the mass of each brick.
Mass of each brick = 1.75 kg
Total mass = 2100 kg
Number of bricks = Total mass / Mass of each brick
Number of bricks = 2100 kg / 1.75 kg
Number of bricks = 1200
Therefore, there are 1200 bricks in 21/4 tonnes.
