A scientist from the United Kingdom claims that the total weight of the mirrors is 1 450 stone. Verify this claim.

There are 91 individual mirrors, and each mirror weighs about 100 kg.

$$\text{Total weight in kg} = \text{Number of mirrors} \times \text{Weight per mirror}$$ $$\text{Total weight in kg} = 91 \times 100 \text{ kg} = 9100 \text{ kg}$$

We are given the conversion: $1 \text{ pound} = 0.45359 \text{ kg}$.
To convert kg to pounds, we divide by the conversion factor.

$$\text{Total weight in pounds} = \frac{9100 \text{ kg}}{0.45359 \text{ kg/pound}}$$ $$\text{Total weight in pounds} \approx 20062.64 \text{ pounds}$$

We are given the conversion: $1 \text{ stone} = 14 \text{ pounds}$.
To convert pounds to stone, we divide by 14.

$$\text{Total weight in stone} = \frac{20062.64 \text{ pounds}}{14 \text{ pounds/stone}}$$ $$\text{Total weight in stone} \approx 1433.05 \text{ stone}$$

The scientist claims the total weight is 1 450 stone. Our calculation shows the weight is approximately 1433.05 stone.
Since 1433.05 stone is not equal to 1450 stone, the claim is incorrect.

The claim is ❌ Incorrect. The total weight of the mirrors is approximately 1433.05 stone.
