Answer: 16 cm^2.
Step-by-step explanation: The volume of a pyramid is equal to one-third the product of the area of the base and the height:

In this case, the base is a square, so its area is:
A=L^2 where "L" is the lenght of the base edge
So the volume would be:


V=16*3/3

Answer:
66%(technically 0.66 repeating)
Step-by-step explanation:
We need to figure out what percentage of 69 equates to 46. In other words, we need to figure out what percentage <u>times</u> 69 equals 46:

Now that we formed this equation, we can solve for the percentage as if it was x.
First lets simplfy:

Now we can solve for x just by getting x alone, which means we must remove the coefficent. We can do this by dividing both sides of the equation by 69:

=

Putting this into the form of percentage, we must multiply by 100. Since, the percentage form of a decimal is 100 times bigger(moved up 2 decimal places):

=
percentage = 66%

Answer:
$900
Step-by-step explanation:
a)Off given on purchasing a TV= 20%
20% on TV = $ 180
Let the original price of TV set $ x
According to question,
20% of x= $180
×x= $180
x = $ 180× 5
x= $ 900
Hence, Original price of TV set= $ 900
b) By second method,
20%= $180
1%= $ 9
100% = $900
Hence, the original price $ 900
