The video tutorial explains how to determine if a block of wood will float without placing it in water by calculating its density. Density is defined as mass per unit volume, and the video demonstrates how to measure the mass using a triple beam balance and calculate the volume by measuring dimensions. By dividing mass by volume, the density of the wood is found to be 0.38 grams per cubic centimeter. Since this density is less than 1 gram per cubic centimeter, the wood will float. The tutorial concludes by reinforcing the concept that objects with a density greater than 1 gram per cubic centimeter will sink.

What is the formula for calculating density?

• Density = Mass x Volume

• Density = Volume - Mass

• Density = Mass / Volume

• Density = Volume / Mass

How is the mass of the block of wood determined?

• By using a digital scale

• By using a triple beam balance

• By using a ruler

• By using a measuring tape

What measurements are needed to calculate the volume of the block of wood?

• Length and height only

• Length, width, and height

• Length and width only

• Height and width only

What is the density of the block of wood?

• 1.00 grams per cubic centimeter

• 0.38 grams per cubic centimeter

• 0.75 grams per cubic centimeter

• 0.50 grams per cubic centimeter

Based on its density, will the block of wood float or sink?

• It will float

• It will sink

• It will neither sink nor float

• It will dissolve
