Question

1. A boy measured a paper weight glass and find the dimension as follows, length is 1 cm, width is 0.8 cm and the is height of 1.5 cm. The mass of the paper weight is 10 grams. Calculate the density of the paper weight.

Answer 1

Step-by-step explanation:

To calculate the density of the paperweight, we need to use the formula: Density = Mass/Volume.

Step 1: Find the volume of the paperweight.

The volume of a rectangular solid (like the paperweight) is calculated by multiplying its length, width, and height. In this case, the length is 1 cm, width is 0.8 cm, and height is 1.5 cm.

Volume = Length x Width x Height

Volume = 1 cm x 0.8 cm x 1.5 cm

Step 2: Calculate the density.

Density = Mass/Volume

Given that the mass of the paperweight is 10 grams (g) and we calculated the volume in the previous step, we can now calculate the density.

Density = 10 g / (1 cm x 0.8 cm x 1.5 cm)

Step 3: Perform the calculation.

To find the density, we need to divide the mass by the volume calculated in step 2.

Density = 10 g / (1 cm x 0.8 cm x 1.5 cm)

Now, you can simplify the expression and calculate the density by multiplying the numbers together and dividing the mass by the volume.
