Calculating Volume and Density

The video tutorial explains how to calculate the density of a regular shaped object. It covers measuring the mass using a top pan balance and calculating the volume by measuring the object's dimensions. The density is then calculated using the formula: density equals mass divided by volume. The tutorial concludes by discussing how the density of the object, compared to water, determines whether it will float.

What two measurements are necessary to calculate the density of an object?

• Volume and temperature

• Mass and temperature

• Mass and volume

• Length and width

Which tool is used to measure the mass of the object in the video?

• Graduated cylinder

• Ruler

• Top pan balance

• Measuring tape

What is the mass of the object as calculated in the video?

• 140.92 grams

• 130.50 grams

• 150.00 grams

• 160.75 grams

How is the volume of the object determined in the video?

• By using a graduated cylinder

• By measuring its dimensions and multiplying them

• By using a water displacement method

• By estimating based on its shape

What are the dimensions of the object used to calculate its volume?

• Width: 6.6 cm, Length: 8.7 cm, Depth: 3.7 cm

• Width: 5.5 cm, Length: 7.7 cm, Depth: 4.7 cm

• Width: 6.6 cm, Length: 9.7 cm, Depth: 3.7 cm

• Width: 7.6 cm, Length: 8.7 cm, Depth: 2.7 cm

What is the calculated volume of the object?

• 200.00 cm³

• 212.45 cm³

• 220.50 cm³

• 230.75 cm³

What is the final calculated density of the object?

• 0.68 grams/cm³

• 0.80 grams/cm³

• 0.90 grams/cm³

• 0.75 grams/cm³

Why does the object float on water according to the video?

• Because its density is greater than water

• Because it is made of a special material

• Because its density is less than water

• Because it is hollow
