a Carver begins work on the following block of granite that weighs 2700g what is the density of the granite ​

Answers

Density" of the given granite block is 2.7g/cm

3

.

Explanation:

Density of an object is defined as the mass occupied per unit volume. “Density” is represented by “ρ”. Mathematically, \rho=\frac{m}{v}ρ=

v

m

where, “m" mass of an object and "v" is volume of an object.

Given that,

Dimensions of the block are 20 cm, 5 cm and 10 cm.

\text { Volume of the block is } l \times b \times h Volume of the block is l×b×h

\text { Volume of the block is } 20 \times 5 \times 10 Volume of the block is 20×5×10

\text { Volume of the block is } 1000 \mathrm{cm}^{3} \text { . } Volume of the block is 1000cm

3

.

Mass of the block is 2700 g.

Substitute the given values in \rho=\frac{m}{v}ρ=

v

m

to find density of a block.

\rho=\frac{2700}{1000}ρ=

1000

2700

\rho=2.7 \mathrm{g} / \mathrm{cm}^{3}ρ=2.7g/cm

3

\text { "Density" of the given granite block is } 2.7 \mathrm{g} / \mathrm{cm}^{3} "Density" of the given granite block is 2.7g/cm

Step-by-step explanation:

Since I don't know what the actual question is, I will solve for the discount:

595 × 22%

Convert percentage into decimal

595 × 0.22

130.9

Discount is 130.9

Now I'll solve for how much that will take off from the original price:

595 - 130.9

464.1

Answer:

5500 ml or 5.5 liters

Step-by-step explanation:

First, we should note that there are 1000 milliliters in 1 liter of liquid.

So, in milliliters, Peter filled three containers with 1500 ml, 750ml, and 2250 ml with 1000ml left over.

To find the total amount, we find the sum of all the milliliters:

1500 + 750 + 2250 + 1000 = 5500 ml

Again, we know that there are 1000 milliliters in 1 liter of liquid, so:

[tex]\frac{5500}{1000}[/tex] = 5.5 liters

5500ml I think that is the answer hope this helps
