## How do you find the volume of a block of wood?

Calculate the volume of the block of wood by multiplying length by width by height for rectangular pieces. Calculate the volume of a cylinder by dividing the diameter by two to calculate the radius. Square the radius and multiply the result by 3.14, and then multiply your product by the length.

**What happens to the density of a material if you have a larger piece of it 1 point?**

In other words, the size or amount of a material/substance does not affect its density.

### Does a wood block have volume?

Mass and volume are physical properties of matter and may vary with different objects. Density has the units of mass divided by volume such as grams per centimeters cube (g/cm3) or kilograms per liter (kg/l). Sample Problem #1. A block of wood has a mass of 8 g and occupies a volume of 10 cm3.

**Why does the same volume of water have a greater density than the same volume of wood?**

If you compared the weight of wood and an equal amount, or volume, of water the sample of wood would weigh less than the sample of water. This means that wood is less dense than water. Since wood is less dense than water, wood floats in water, no matter how big or small the piece of wood is.

## What is the volume of block?

The volume of a block, prism, or cylinder is easily calculated by multiplying the area of the base by the height/altitude of the object. When the bases are not parallel, the height or altitude of the object is from the center point of one base to the center point of the other base.

**What is the volume of wood?**

The volume of wood is the length of the pole times the cross-sectional area. A circle (the cross-section) has an area equal to π times the square of the radius. The radius is the circumference divided by 2π. Thus your volume of wood in cubic feet is 20 × 52 ÷ (4π).

### What happens to the density of a block when you change the volume?

If the mass of the object stays the same but the volume of the object decreases then its density becomes greater. If the volume of the object stays the same but the mass of the object increases then its density becomes greater.

**Does volume change with shape?**

Summarize the idea that volume is the amount of space an object takes up. As long as we don’t add any material or take any away, the volume will stay the same even if we change the shape of the object.

## What are the units of volume of a wood block is you are measuring using a rule?

The volume of the block is represented by the formula: Volume = length × width × height. Therefore, you would do the following calculation: Volume = 1.2 cm × 1.0 cm × 1 cm = 1.2 cm.

**What happens if the density of the object is equal to that of the fluid?**

Answer: If the density of the object is equal to the density of the liquid, the object when placed in the liquid would have neutral buoyancy. The object when placed in the liquid would sink until it was submerged and then would only move up or down if acted on by forces other than buoyancy.

### Which part of the water has a greater density lesser density?

Water density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least dense at 0°C (freezing point).

**What happens to the water level when you drop a stone?**

Does it rise, fall or stay the same? I’d say that the water level drops, because when you drop the stone in the lake, the water level rises according to the volume of the stone, BUT the water level decreases by a volume of water weighting the stone’s weight, when you take it off the boat. Is that correct?

## How does a rock’s volume change in a lake?

Like you say, on the boat, the rock displaces its weight in water. In the lake, the rock displaces its volume in water. The latter is less displaced water than the former, because the rock is denser than water.

**How do you calculate the volume of wood submerged in water?**

So V, the volume of the wood, the entire volume, not just the amount that’s submerged, times the density of the wood times gravity must equal the volume of the wood submerged, which is equal to the volume of the water displaced times the density of water times gravity.

### What happens when a rock is at the bottom of water?

When the rock is at the bottom of the water, it displaces its volume in the water rather than the weight. Due to the fact that the rock’s density is greater than that of water and volume, the water level will fall. Highly active question.
