Given a cube with a volume of 27cm3, what is the volume of a square pyramid?

Mathematics

VashaNatasha [74]3 years ago
5 0

First from the information we have, we see that the volume of the cube is 27cm3. So what are the dimensions of its length, width and height? This information will help us to determine the dimensions of the square pyramid.


Volume of a cube is found from the formula  V = a3


Where V is volume, and a is the length of one side.


We expand this equation to be:


V= a * a * a


Since all sides of a cube are equal, then this equation will be:


27 = 3 * 3 * 3


Now we know the length width and height of the cube.


Volume of a  square pyramid is given by the formula V =1/3ah


Where V is the volume, a is the area of the base of the pyramid, h is the height of the pyramid.


Since it fits perfectly into the cube, then its dimensions are the same as the cube, so:


Area of the base is Length * Width so:


a = 3 * 3 = 9


and height:


h = 3


Now therefore:


 V =  1/3 * 9 * 3


V = 1/3 * 27


V = 27/3


V = 9 cm3

Write two fractions that have the same value as 1/2.Explain how you know they have the same value
BaLLatris [955]

Answer:

2/4 3/6  and more

Step-by-step explanation:

the reason is that for and example 2/4 if you divide both the numerator (top) and the denominator (bottom) by 2 it equals 1/2. So 2 divided by 2 is 1 and 4 divided by 2 is 2 . Another example is 3/6 because 3 divided by 3 is 1 and 6 divided 3 is 2.

There is a 10% off sale on laptop computers. If someone saves $35 on a laptop, what was its original cost?
IceJOKER [234]

Answer:

The original cost is $350

Step-by-step explanation:

Let's assume

original cost of computer is x

There is a 10% off sale on laptop computers

So, amount saved is

=\frac{10}{100}x=0.10x

now, we are given

someone saves $35 on a laptop

so, we can set them equal

and then we can solve for x

0.10x=35

we can divide both sides by 0.10

and we get

x=350

So,

The original cost is $350

Please help me with #1
jasenka [17]

let apple juice = x

 milk = 2x

 fruit punch = 3x

3x + 2x + x = 660

6x = 660

x = 660/6

x = 110 apple juices

2*110 = 220 milks

3*110 = 330 fruit punches
