Density and Volume Calculations

This video tutorial explains how to calculate the density of regular-shaped objects, such as cuboids, by measuring their mass and volume. The process involves using a scale to find the mass and measuring the dimensions to calculate the volume. The video demonstrates this with a wooden block and a brass block, showing the calculations and comparing their densities. The tutorial emphasizes the importance of using a calculator to avoid errors and explains the significance of units in density calculations.

What is the formula for calculating density?

• Density = Volume / Mass

• Density = Mass x Volume

• Density = Volume - Mass

• Density = Mass / Volume

How do you calculate the volume of a cuboid?

• Length x Width x Height

• Length x Width

• Width x Height

• Length + Width + Height

What is the volume of the wooden block in the video?

• 50.84 cm³

• 56.84 cm³

• 60.84 cm³

• 66.84 cm³

What is the mass of the wooden block?

• 59.65 grams

• 39.65 grams

• 49.65 grams

• 69.65 grams

What is the density of the wooden block rounded to two decimal places?

• 0.80 g/cm³

• 0.90 g/cm³

• 0.70 g/cm³

• 0.60 g/cm³

Why is the brass block denser than the wooden block?

• It has a lower volume.

• It is made of a lighter material.

• It has a greater mass despite being smaller.

• It is larger in size.

What is the mass of the brass block?

• 158.8 grams

• 168.8 grams

• 178.8 grams

• 188.8 grams

What is the volume of the brass block?

• 29 cm³

• 25 cm³

• 19 cm³

• 15 cm³

What is the density of the brass block rounded to two decimal places?

• 8.76 g/cm³

• 8.86 g/cm³

• 8.96 g/cm³

• 9.06 g/cm³

Which block has a higher density?

• Wooden block

• Cannot be determined

• Brass block

• Both have the same density
